I am building a lightweight ERP and would like you to tackle the Accounting & Finance side first. The core requirement is a robust Financial Reporting feature: balance sheet, P&L, cash-flow statements and the usual drill-down capability that lets users trace each figure back to the underlying journal entry. Inventory or Payroll are outside the initial scope, though the code should remain modular so those areas can be added later without refactoring the entire stack. Your job starts with the data model – chart of accounts, journals, multi-company support and period locking – and moves through to the reporting layer. I expect clean APIs (REST or GraphQL), a responsive web interface built with a modern front-end framework, and role-based security. Please lean on open-sour...

I’m a full-stack web developer with three years of hands-on experience in React, Node.js, , PostgreSQL, JavaScript, and Shopify/Liquid. My portfolio () showcases custom dashboards, performant APIs, and conversion-focused Shopify stores. What I need now is a reliable partner who can consistently connect me with paying clients. Your focus will be on the e-commerce space—brands that want new online stores, feature upgrades, or complete rebuilds. Whether the prospect needs a streamlined Shopify setup or a fully custom solution, I can handle the development while you handle the outreach. Although our primary target is e-commerce, I’m open to opportunities in healthcare or education if you come across them, so feel free to pitch widely when it makes sense. Ideal prospects: &b...

I’m building a new application and need a Laravel specialist to handle the entire backend. The core pillars are: • User authentication – secure registration, login, password reset, and role-based access. • Database management – design the schema from scratch, write migrations and seeders, and wire everything up to a fresh MySQL instance. • API creation – clean, well-documented REST endpoints that the front-end team can consume straight away. Laravel 10 is preferred so we can rely on the latest features and long-term support. Feel free to integrate Sanctum, Passport, or another token solution you’re comfortable with for authentication, as long as it stays native to the Laravel ecosystem. Deliverables 1. Fully functional Laravel project pus...

I’m setting up an online presence for my car dealership and export business and need a website built from the ground up that also functions as a light ERP. The public side must display vehicles attractively, let visitors filter, inquire, and, eventually, complete purchases, while the back-office keeps inventory, customers, sales, and export paperwork in one place so I never enter data twice. What I’m after • A modern, responsive design that matches an automotive brand. • A connected ERP module (Odoo, Dolibarr, SAP B1 API, or a custom PHP/Laravel build—tell me what you prefer) covering inventory, customer records, orders, payments, and shipping docs. • Seamless data flow between front-end and ERP. • Core e-commerce functions ready now, with roo...

I am looking for an experienced C# / ASP.NET Core developer to build a production-quality REUSABLE CORE V1 that will become the starting point for multiple future SME client applications. This is NOT a prototype or generic CRM template. I handle client discovery, business analysis and requirements. Your role is to implement a clear specification, test it properly and deliver maintainable code another competent ASP.NET developer can continue later. V1 SCOPE - Authentication / users / simple permissions - Clients - Vehicles - Search, filters, sorting, pagination - Exports and basic history - Polished responsive business UI - Strong reusable technical foundation Future modules such as Scheduling, Quotes, Work Orders, Catalogue and Stock are OUT OF SCOPE. All visible UI text must be Europea...

My SaaS is running on a “Lovable” stack and I already hold active accounts with both Paddle and Lemon Squeezy. What I need now is a clean, production-ready integration that: • Lets new and existing users choose a plan and pay through either provider • Creates and maintains their recurring subscriptions automatically • Syncs status changes (upgrade, downgrade, cancel, failed payment) back to my app in real time Please wire up the REST APIs, webhooks and any server-side logic so that revenue lands in my personal payout accounts exactly as Paddle and Lemon Squeezy allow. I will expose the current user, plan and license tables plus a staging environment as soon as we start. Acceptance will be simple: a test user can subscribe, renew, upgrade and cancel on bo...

We are looking for an experienced mobile app developer or development team to build a modern mobile application for a coffee shop. The main purpose of the app is to allow customers to browse the menu, customize their drinks, place orders, pay online, collect loyalty points, and receive offers and notifications. The application should be simple, fast, modern, and easy to use. Main Customer App Features: * User registration/login using mobile number or email * Guest browsing * Coffee shop menu with categories * Product images, descriptions, sizes, and prices * Product customization, such as: * Size * Hot / Iced * Milk type * Extra shots * Syrups * Sugar level * Additional options * Add to cart * Checkout * Pickup orders * Option to schedule pickup time * Online payment int...

I need a clean, reliable approval workflow that plugs seamlessly into both our existing web application and the companion mobile app. The flow is strictly for internal staff: a team member submits new-customer details, a manager reviews the record, and a final approver signs off before the account is activated. The core logic must: • Capture and store each stage (Initial submission → Manager review → Final approval) with full audit history. • Trigger real-time email or in-app notifications so no step stalls. • Expose REST/GraphQL endpoints that our front-end teams can call from React (web) and Flutter (mobile). • Respect role-based access controls already in our PostgreSQL DB. Deliverables I expect: 1. Database schema updates and migration scri...

I need a small, dependable solution that watches a specific website’s booking flow and immediately triggers mobile-app push notifications whenever a new slot, confirmation, or status change appears. Email or SMS are not required; push notifications are the sole channel. I don’t need a full-blown dashboard—basic, hard-coded configuration is fine as long as I can adjust the key parameters in a file or a few constants. Core expectations • Monitoring logic that reliably detects the booking events I will specify (e.g., page change, API response, or DOM element update). • A lightweight back-end or background script that pushes the alert through a standard mobile push service (Firebase Cloud Messaging or an equally straightforward alternative). • Clear setu...

My current Kodi addon was generated with AI and, while functional, it still falls short of what I need. I want to push it further in two key areas: adding meaningful new capability and squeezing every bit of performance out of it. The headline feature I’m after is a clean merge with the Mad Titan Sports V2 addon so that my users can access its live-sports streams without having to install a second plugin. I’m happy for the codebase of Mad Titan Sports V2 to remain intact as long as the final experience feels seamless—one settings panel, one set of menus, one consistent UX. Alongside the merge, I expect typical performance work: quicker navigation, reduced startup latency, and lighter memory usage on lower-powered Android boxes. Please retain full compatibility with Kodi...

I currently have a website that does not require user authentication or sign-in. I have also developed an Android app that similarly does not support user sign-in or authentication. Before proceeding with the Android app deployment to the Google Play Store, I am considering implementing a sign-in system so that users can create accounts and access personalized features across both the website and the mobile app.

Software tool for merchandisers I want an app that helps merchandisers find the items they merchandise. The app must accurately display the locations of each item no matter how small or big it is through either its article number or its barcode. I want the app to be able to link to multiple company databases but never without the proper authorisation from the company itself. It must only pick up items once scanned in by that companies stock controller and must work in synchronisation with the company system to track where the stock is at all times up until it is scanned by the till point. Once checked out by the till point, it must no longer display where the item is. The app must be able to work seamlessly with whatever company system it comes into contact with. Your job will be to figu...

# Affiliate / Vendor Campaign Tracking Platform – MVP **Budget: ₹8,000 – ₹10,000 INR** We are looking for an experienced developer to build an **Affiliate / Vendor Campaign Tracking Platform** for our performance marketing business. The platform will be used to manage clients, campaigns, vendors/publishers, tracking links, conversions, postbacks and campaign performance from one central dashboard. This is **not an influencer marketing platform**. It is primarily an affiliate/performance marketing tracking system. ## Main Requirements ### 1. Admin Dashboard We need a simple and easy-to-use admin dashboard where we can manage: * Clients * Campaigns * Vendors/Publishers * Tracking links * Conversions * Reports * Campaign status * Caps and limits * Revenue and cost * Profit...

I need a compact, production-ready WordPress plugin that scans posts, pages, and any registered custom post type for broken internal links only. The checker must hit the usual HTTP status codes—200, 301, 404, 500—and flag redirects while making sure the same URL is never tested twice. All network activity has to run through asynchronous, non-blocking requests so the front-end remains untouched and PHP time-outs are a non-issue on sites with tens of thousands of records. Inside the admin you’ll surface a lightweight dashboard that shows a basic summary of error counts per status, offers one-click manual re-scans, and stores a concise scan history. WP-Cron should trigger scheduled scans at an interval I can adjust, and there must be a simple “ignore” toggle so ...

I want to launch a lightweight chat application, inspired by the conversational feel of Quora but focused purely on messaging rather than full-blown forum threads. The core build needs to run natively on both Android and iOS and I’d like Claude AI to be used wherever it can accelerate clean, maintainable code (for example code generation, content moderation, or smart reply suggestions). Core scope • One-to-one user messaging and multi-user group chats. • Seamless file sharing inside any chat (images, docs, short clips). • Social-media-based authentication so new users can sign up in seconds. • Simple “status update” feature so people can post what they’re up to, visible to their contacts. Tech expectations You’re free to choos...

I need a single Android application that seamlessly blends three experiences: a full-featured shopping portal, a robust bill-payment hub, and a stored-value wallet. For the wallet, real money movement is essential. Users must be able to add funds straight from their bank accounts and through a payment-gateway top-up flow, see every credit or debit in a clear transaction history, and send money to other users instantly. The shopping side should feel like any modern e-commerce app: a browsable product catalog, an intuitive cart (with quantity edits and promo-code entry), and a wishlist that persists across sessions so shoppers can save items for later. When a user checks out, the wallet balance should appear as a payment option alongside any external gateways. Bill payments should f...

Saya sedang memulai sebuah inisiatif baru dan membutuhkan dua hal utama: 1. Pengembangan perangkat lunak - Saya sudah memiliki konsep dasar dan beberapa alur kerja yang ingin diwujudkan. - Fokus awal adalah membangun fungsi inti yang stabil; setelah itu kita bisa memperluas fitur secara bertahap. - Kode harus bersih, terdokumentasi, dan mudah dipelihara. 2. Desain logo bergaya minimalis - Logo harus simple, mudah diingat, dan tetap terlihat kuat baik di latar terang maupun gelap. - File akhir yang saya perlukan mencakup versi vektor (SVG/AI) serta PNG transparan dalam resolusi tinggi. Kualitas, komunikasi yang jelas, dan kemampuan memberi saran perbaikan sangat penting bagi saya. Jika Anda nyaman menangani kedua kebutuhan sekaligus—atau memiliki rekan desa...

Saya berencana membuat sebuah platform digital yang berfokus pada penyediaan informasi bagi pengguna. Jenis platform belum saya kunci, jadi saya terbuka pada saran—bisa website, aplikasi mobile, maupun solusi gabungan selama pengalaman membaca konten lancar dan mudah diakses. Yang saya butuhkan: • Rekomendasi arsitektur dan teknologi terbaik untuk tujuan “menyediakan informasi”. • Rancangan struktur konten (mis. kategori, tagging, dan fitur pencarian sederhana). • Desain antarmuka awal yang ramah pengguna. • Implementasi versi pertama yang fungsional beserta dokumentasi instalasi. Silakan sertakan portofolio singkat proyek serupa dan perkiraan timeline Anda.

I’m looking for a straightforward control panel that ties into my Telegram groups and handles every add-and-remove task for me. The flow is simple: I define the rules, the system watches the group, and it automatically brings new users in or takes inactive/expired users out—no manual clicks from my side. Core expectations • Full automation of member addition and removal through the Telegram Bot API (or any reliable library you prefer). • Rules are the engine: I want an interface where I can create, edit, and prioritise the predefined rules that decide who comes in or goes out. • Real-time status feedback: show me success/failure logs so I can confirm the bot is doing its job. • Secure, login-protected web panel that I can run on my own VPS. Deliver...

I need an experienced developer to take a deep look at my Android application and the server calls that power it, then tune both sides so the user experience feels instant and light. Right now the app shows occasional frame drops, long cold-start times, and higher-than-expected RAM usage. I want measurable gains in speed and responsiveness without sacrificing stability, plus a clear reduction in memory footprint. What you’ll actually do • Profile the APK with Android Studio Profiler, Systrace, and (if you prefer) tools such as Firebase Performance or LeakCanary to isolate hot paths and leaks. • Review the API layer and suggest tweaks—batching, caching, pagination, or server-side query changes—so network latency no longer blocks the UI thread. • Refac...

I’m ready to turn several reliability-engineering methods—FMEA, FMECA, FTA and general reliability analysis—into one seamless online workspace. You’ll take the concept sketches and calculation logic I already have and translate them into a full-stack, production-ready web app built on a modern framework such as React or Angular. Core requirements • Modular data-input screens that let users build, edit and clone analyses quickly. • Real-time calculations that generate automated risk-priority reports and downloadable summaries (PDF/Excel). • Interactive visualisation: Pareto charts, fault trees, heat maps and trend graphs rendered with a charting library of your choice (e.g., D3.js, ). • Secure sign-up, login and granular role management s...

I run a live site and I’d like to bring on a reliable developer who can stay with me month-to-month. Your job is end-to-end: keep what is already online stable, design and ship new user profile pages whenever I request them, and adjust the database architecture so each new feature fits smoothly into production. Here’s what the collaboration will look like: • Monthly cadence, capped at roughly a USD 50 retainer. • You tackle both front-end (React / , Tailwind or similar) and back-end work (API routes, schema updates, deployment tweaks). • When I ask for a new user profile flow—say an extra tab, a fresh settings section, or improved data retrieval—you’ll spec it out, build, test, and push it live. • Code should stay clean and version...

I need a single, fully-integrated CRM platform that lets one person run my entire law firm with AI handling every routine and data-heavy task. From the first touchpoint with a prospect right through to closing the matter—and then on to HR, accounts, compliance, and ongoing client care—I want the system to think, draft, remind, route and report without constant human supervision. Key functions the agents must own • Lead generation and qualification, including outreach sequencing via our email system. • AI-assisted legal drafting that pulls data from our document-management repository and populates templates automatically. • Human-resources workflows such as candidate screening, onboarding checklists and performance reminders. • Any remaining module...

I have an existing front-end ready to go and now need a solid Python backend built and put online. Please architect and code the server side in Python—feel free to choose the framework you are most comfortable with (Django, Flask or FastAPI all work for me) as long as it is scalable and well-structured. Core expectations • Develop clean, well-documented code that exposes all required endpoints so the front-end can log users in, store and retrieve data, and talk to third-party services. • Set up a production-ready database and handle migrations. • Configure, secure and deploy the application on a reliable cloud host. I did not lock us into AWS, GCP or Azure, so recommend the platform that best fits the stack you build. • Hand over deployment scripts (Docke...

Merhaba, Kitantik mağazam için basit bir ürün yükleme otomasyonu yaptırmak istiyorum. İstediğim sistem şu şekilde çalışacak: 1. Telefon veya bilgisayardan ürün/kaset fotoğrafını sisteme yükleyeceğim. 2. Fotoğraftaki renkli sticker algılanacak. 3. Sticker rengine göre daha önceden belirlediğim fiyat otomatik atanacak.

I’m building a cross-platform social networking app and need a React Native developer who is equally comfortable crafting the companion Node.js backend. The first release centres entirely on real-time messaging, so everything you create should be optimised for quick, reliable exchange of: • Text chat • Voice messages • Video calls You’ll wire up the mobile UI in React Native, handle state management, notifications and media capture, then connect it to a Node.js server (WebSocket or similar) that you configure for secure, scalable delivery. Although user profiles or a news feed may come later, for now the focus is a smooth chat experience that feels instantaneous, works on both iOS and Android, and is ready to grow. Deliverables will include the full Reac...

I need a custom-built stock-tracking application that lets me record incoming stock, log each outgoing movement, and see an accurate closing balance at any moment. The core will be a web-based system so I can access it from any browser, yet it also has to run smoothly on both iOS and Android phones—either as a fully responsive web app or a wrapped hybrid build. Key expectations: • Simple screens to add, edit or remove stock items in real time • Instant calculation of available and closing quantities after every transaction • Search and filter functions so I can trace a product’s movement history quickly • Secure user sign-in with separate roles for admin and regular staff • Clean summary reports that I can export or print I’m open to yo...

I’m building a small-scale learning platform and need everything assembled into one seamless ecosystem. On the mobile side I want native apps for both iOS and Android that let students log in securely and browse/download their course materials right from their phones or tablets on payment of fees online.A clean, distraction-free UI and smooth offline reading will help keep engagement high. Additionally I need live lectures from big blue button. Basically we like to run a coaching academy. For the web, the first milestone is a responsive site where new learners can complete their own student registration. Once registered, the same credentials must carry over to the apps so users have a single sign-on experience across all devices. Core expectations • Shared database or AP...

I need a polished, production-ready Android application focused entirely on e-commerce. The core requirement is a smooth buying journey—from browsing products, adding items to a cart, and completing a secure checkout, through to receiving order confirmations and basic status updates. The app must be native for Android (Kotlin or Java are both fine) and follow current Material Design guidelines so it feels at home on modern phones and tablets. I already have product data and imagery prepared; what I need is the technical build, an intuitive UI/UX, and connection to a payment gateway such as Stripe or Razorpay. Please include: • Clean, well-commented source code hosted in a private Git repository • A fully signed, Play-Store-ready APK or AAB • Simple admin or...

I’m putting together a straightforward location-tracking system for loads of non-perishable goods that move through warehouses, trucks, and rail cars. The core requirement is real-time position updates from departure to storage, with automatic alerts if a device signals potential theft. The hardware can be either single-use—so the receiver never has to return or recharge the tag—or a reusable unit that we can redeploy after each trip. I’ll need your help scoping both variants and producing an estimated cost per device for each. What I expect from you • A concise technical proposal outlining the recommended tracker form factor, network technology (e.g., GSM, LTE-M, NB-IoT, LoRaWAN), and back-end platform or API you plan to leverage. • A table or brie...

I need a fully compliant, multi-platform ELD system built from the ground up for U.S. trucking operations. Drivers must be able to edit logs easily, generate DVIRs automatically, and keep every HOS event audit-ready. On top of those core functions, I want machine-learning capability that flags potential violations in real time, forecasts remaining hours, and suggests smarter break or dispatch options before problems arise. The solution has to live everywhere my team does, so plan on native iOS and Android apps for drivers and a responsive, Web-based dashboard for dispatch and compliance staff. I’m open to the languages, frameworks, and cloud stack you believe will scale best—just explain why your choice makes sense for low-latency Bluetooth/vehicle-bus connections, AI workload...

I need a colour-prediction game built specifically for Android phones. The app should feel lightweight and intuitive for end-users while giving me complete control through a secure web-based admin panel. Core play: users predict the next colour, stake virtual coins, and instantly see the outcome. An in-game currency wallet must handle balance updates, bet deductions, and winnings in real time. All coin movements should be recorded for audit and displayed clearly to each player. Admin panel: from any browser I want to create or close rounds, adjust win ratios, credit or debit coins, view player histories, and export basic reports. Role management for additional operators would be a plus but is not mandatory at launch. Technical notes • Target device: Android (phones and tablets). ...

SuperLink ISP CRM is designed to manage ISP operations from a centralized platform, including customers, sites, network connections, tickets, billing, payments, credentials, quotations, and operational workflows. The existing application is already developed using a modern PERN + TypeScript architecture, and I am looking for professional-level improvements, bug fixing, feature enhancement, UI/UX refinement, security improvements, and production optimization. ### Project Objectives The main objective is to make the platform more polished, reliable, scalable, secure, and production-ready for real-world ISP op...

I am looking for an experienced Full Stack Developer to review, improve, optimize, and enhance my existing real-time chat application, VChaTie. VChaTie is a modern WhatsApp-style real-time messaging platform built with a React frontend and Django backend. The application uses WebSockets and Django Channels for real-time communication and Redis for handling real-time messaging infrastructure. The project is already developed, and I am looking for professional-level improvements rather than building the application from scratch. ### Project Goals The main goal is to transform the existing VChaTie application into a polished, scalable, responsive, and production-ready real-time communication platform. ### Required Work #### 1.

I need a Telegram bot that can sell my research-use peptides directly inside the chat. The essential feature is a smooth product catalog where buyers can browse items, add them to a cart, and pay through Stripe without leaving Telegram. Here’s the flow I have in mind: a user starts the bot, browses peptides by category, selects quantities, confirms shipping details, and receives a Stripe checkout link. Once payment is confirmed via Stripe’s webhooks, the bot should notify me in Telegram (and optionally email) with the full order details. An admin interface—either inline in Telegram or a lightweight web panel—must let me add, edit, or remove products, update prices and stock, and review order history. I don’t need order tracking or live customer support right...

I need a clean, well-structured Python OPC-UA client that can talk directly to an SLM 280 metal 3D printer and give me full, real-time control over its atmosphere management: O₂ concentration, chamber pressure, and gas flow. The end goal is to adjust those three parameters remotely and watch them update live, as if I were standing in front of the machine. Scope – Establish a reliable OPC-UA connection to the printer’s server nodes. – Expose read/write methods so I can both query and set O₂, pressure, and flow values without latency that would compromise print quality. – Wrap the interaction in a clear API layer (class or module) so future scripts can call it with one or two lines. – Handle connection drops gracefully and log every transaction for trac...

Hi, I can build this as a compact, reliable web application focused specifically on the business workflow you want to automate, rather than overengineering it into a large platform. My preferred stack would be Python with FastAPI/Django, PostgreSQL where needed, and a lightweight browser-based frontend, with Git-based source delivery and clear deployment documentation. I have built and deployed multiple backend/API projects involving automation, background processing, databases, authentication, testing, and deployment. In particular, my AI Agent API handles automated workflows using Python, APIs, PostgreSQL, Redis, and Celery, while my SaaS and marketplace APIs demonstrate experience building maintainable web systems. I can provide: - Complete source code in Git - Working web applicati...
