Daripada 244,036 ulasan, klien menilai Java Developers 4.9 daripada 5 bintang.I have the code that is fully tested and working website that needs to be migrated and deployed on to a VPs server…host is well known it is a little jibe just need some quotes it is a spring boot website with database. Here is what I expect: • A minimal but complete codebase that compiles and runs with a single `./mvnw spring-boot:run`. • All database connection details externalised in ``, ready for me to swap in my own credentials. • A SQL script (or Flyway/Liquibase migration) that creates the necessary schema and seeds a couple of sample rows so I can see data flowing end-to-end. • Simple HTML (Thymeleaf or similar) served from the backend—no heavy frontend build pipeline is needed. • Clear README instructions covering project structure,...

I’m ready to have a full-featured web application built that focuses on e-commerce. The core of the project is straight-forward: a clean, responsive storefront where customers can browse products, add them to a cart, and complete secure check-out. I’m open on the tech stack as long as it’s mainstream, well-documented, and future-proof, so feel free to propose what you’re most comfortable with—whether that’s a JavaScript framework like React or Vue paired with Node.js, or a Python/Django or PHP/Laravel back end. Key elements I need: • Robust product and inventory management • User-friendly shopping cart and checkout flow • Secure payment gateway integration (Stripe or similar) • Admin dashboard for order tracking, refunds, and ...
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.
I need a clean, well-optimised Minecraft item model produced in Blockbench for the Java Edition. The mesh should stay within vanilla-style proportions so it feels right in-game, but I still want just enough extra detail to make it stand out in a resource pack. You’ll handle both the model and its texture, keep the poly count sensible for Java, and export a ready-to-use .json together with the .bbmodel source so I can tweak it later if I need to. Deliverables: • Finished Blockbench (.bbmodel) file • Associated texture PNG • Exported item .json configured for Java Edition As long as you’re comfortable with Blockbench and familiar with Minecraft’s item rendering conventions, this should be straightforward. Just let me know your timeframe and any examp...
I need a lightweight Android Accessibility Service that silently accepts incoming ride requests inside the Ola Driver app. The service must: • Detect the ride-request pop-up and perform a single, human-like tap on the accept button. Tap coordinates and delay have to vary a little on every press so the behaviour looks organic. • Stay active only while the Ola Driver app is in the foreground and I am online; it should pause automatically when I switch the app offline. • Run unobtrusively in the background, start on boot if possible, and ask for the minimum permissions required. Deliverables • Installable APK plus complete Android Studio project with clean, well-commented source. • Step-by-step guide showing how to enable and test the Accessibility Service. ...
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...
I need a complete Android-native marketplace app built from the ground up. The goal is to let multiple vendors list products while customers browse, purchase, and track orders in one seamless experience. Scope • Plan and refine the overall user flow for buyers and sellers. • Design an intuitive, modern UI that follows current Material Design guidelines. • Build core marketplace modules: product catalog, vendor dashboard, cart and checkout, order management, and basic analytics. • Implement a clean, well-documented REST or GraphQL API so the mobile front-end remains fast and future-proof. • Include an admin panel (web or mobile) where I can onboard vendors, approve listings, run promotions, and review transactions. • Provide full source code, build...
I want a complete Chess game built in Android Studio with clean, well-commented code so that I can study and extend it later. The project must implement every official rule of chess: legal piece movement, check and checkmate recognition, castling (both sides), pawn promotion to any major piece, and the ability to undo the last move. The look and feel should follow a classic user-interface style, pairing naturally with a traditional wooden board and pieces. While I prefer that timeless aesthetic, the architecture should be flexible enough that I can swap in alternative themes later if I choose. Gameplay has to feel smooth and professional. Fast, responsive touch controls are essential, and performance should remain solid even on older Android devices. Subtle animations are welcome as lo...

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 building a new phone and my top priority right now is the Android software. Specifically, I need a fully-functional custom user interface that can be flashed onto the device and demonstrated on current Android hardware. The UI should: • Replace the stock launcher and system theme with a distinctive visual identity that matches the industrial design of the phone • Run smoothly on the latest AOSP release and remain compatible with upcoming versions • Include core screens (home, app drawer, notification shade, quick settings, settings menu) with fluid animations and Material-next styling • Support essential Google Mobile Services integration so standard apps behave normally Deliverables 1.

I have a concept tentatively called “From 100 t” that I want turned into a fully functional Android application. The idea is still at an early stage, so I’m looking for someone who can guide the entire mobile build-out—from defining a clean architecture to publishing a polished APK on Google Play.

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 enhancing an existing Java-based web application and need a junior-level developer located in India to focus purely on the front-end layer. Your day-to-day work will revolve around turning the current UI mock-ups and JSP templates into clean, responsive pages written in standard HTML, CSS and vanilla JavaScript, ensuring they plug smoothly into the already-built Java web stack. You will receive clear design files, access to the project’s Git repository, and a short onboarding call to walk you through our coding conventions. From there, I’ll expect: • Pixel-accurate screens rendered across modern browsers • Lightweight, well-commented CSS with mobile responsiveness baked in • JavaScript kept framework-free unless a use case demands otherwise &bul...
I want an Android app that lets me jot down every Forex position I take during the day and instantly shows whether I closed it in profit or loss. The flow should be as quick as opening the app, tapping “Add Trade”, entering the pair, lot size, open and close price, then saving—nothing bloated or confusing. Core behaviour • Each trade is stored with its profit-or-loss figure. • The moment a trade is saved, that P/L appears right on the trade row so I can scan the day’s list and see how I did, trade by trade. • A clean, modern Material-style UI that looks native on recent Android versions. I’m not after heavy analytics or alerting systems yet; the priority is reliable trade logging and a clear per-trade profit/loss display. Data can sit lo...
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). ...

I need an Android-first cooking application that ships with a polished, searchable recipe database, a built-in grocery list manager, and an adjustable cooking timer that can run in the background while users browse other screens. For now, those three core features are non-negotiable. I am still weighing whether to let users create and share their own recipes, so I would like the codebase structured in a way that makes adding user-generated content straightforward in a later update (for example, keeping data models and cloud storage hooks modular). Deliverables • Production-ready APK and Play-Store-ready bundle • Clean, well-commented source code (Kotlin or Java inside Android Studio) pushed to a private Git repo • Basic Firebase or Room database setup for recipes...
Mobile app needed in java, android studio with AI work from Pakistan or India new freealncer for some easy work
I need a production-ready AES implementation that I can drop into our stack to protect data at rest. The focus is on clean, well-documented source code that supports 128, 192, and 256-bit keys, CBC and GCM modes, plus straightforward hooks for key rotation. My environment is a mix of Python micro-services and a Java back-end, so a portable C/C++ core wrapped for those languages—or native, equally secure versions—would work. What matters most is that the code passes standard NIST test vectors, includes unit tests, and ships with a concise integration guide. Deliverables: • Fully commented AES library (source + build instructions) • Test suite confirming compliance with FIPS/NIST vectors • Short README covering integration and key management reco...
I need an end-to-end algorithm that trades a single share-market instrument entirely on technical chart analysis. The core logic must follow a technical trading approach, relying on candlestick patterns, moving averages, RSI, and manually-defined trend lines to decide entries, exits, and position sizing. Scope The build starts from raw market data ingestion, moves through signal generation, and finishes with live order execution and performance reporting. All elements—data cleaning, feature engineering, back-testing, walk-forward validation, risk controls, and real-time monitoring—should sit inside one coherent codebase so I can flip from historical tests to live trading with minimal re-configuration. Implementation Notes • Python is my preferred language; common...
Overview: We require a production-grade automation service that monitors an incoming Gmail inbox, reliably extracts structured work-order data using an LLM, and creates fully populated Jobber Requests via Jobber's GraphQL API. Key Functional Requirements: 1. Ingestion: - Real-time email capture using Gmail API via Google Cloud Pub/Sub webhooks (no inefficient polling). - Robust handling of forwarded/nested email threads to extract the original requester's details, not the forwarder. 2. AI Extraction & Validation: - LLM pipeline (OpenAI/Anthropic) using strict JSON schemas (Structured Outputs / Tool Calling). - Extracted fields: Client Name, Phone, Email, Property Address, Job Title, Work Overview, and Job Notes. 3.

I am a YouTube content creator with an existing gaming audience of 7,600+ subscribers, and I am looking for a highly skilled developer who can become a long-term development partner for a large-scale mobile multiplayer roleplay game. About the Project The goal is to build a GTA/SAMP-style mobile multiplayer roleplay experience, inspired by the depth and systems of games such as Black Russia and SA-MP. I have extensive knowledge of multiplayer roleplay games and understand the gameplay and systems required, including: - Roleplay systems - Economy and jobs - Vehicles and properties - Factions and organizations - Police/criminal systems - Character progression - Businesses - Inventory systems - Multiplayer gameplay - Server-side game systems - Player management - Monetization and live-se...
I have a fully-working Android Studio project (Java) that photographs urine test strips and reads the colours, but its interpretation layer is letting us down: colours are detected correctly, yet the final numbers it returns are wrong. I need someone to dig into the existing code, locate the flaw in the result-interpretation logic, and at the same time refine the overall algorithm so the readings become clinically reliable. Because I’m interested in both fixing the bug and improving the core method, you will be free to refactor, recalibrate, or even redesign parts of the analysis pipeline provided the camera capture and colour-extraction steps remain intact. OpenCV and native Android APIs are already integrated, so you will be working inside that framework. Key deliverables: &bul...
I need a robust automation bot for an Android game that can do three core things: 1. Detect every relevant UI element on multiple screens through image recognition, then tap the right spots to claim the daily rewards without fail. 2. Autonomously solve the in-game maze and pick-pair minigames with human-like speed and accuracy. 3. Run hands-free once launched, logging what it collected or solved so I can review a simple report afterward. Deliverables • Full Android-ready build (APK or script + instructions to run with ADB/Emulator) • Source code with clear comments • Image libraries or model files used for recognition • Quick user guide and a short demo video that shows the bot clearing both minigames and collecting a day’s rewards Acceptance criter...
I need a complete Android mobile application that serves as a social media platform. The core task is to turn my concept into a fully functioning app—from setting up the project in Android Studio, through coding the main social features, to packaging a release-ready APK. At this stage I will provide the feature list, brand assets, and any required APIs; you’ll transform them into clean, well-documented Kotlin or Java code. Expect typical social elements such as user registration, profile pages, a scrolling feed, basic post interactions, and push notifications, but I’m open to your technical guidance on the best architecture and libraries. Deliverables • Full Android Studio project with readable, commented source code • Signed release APK and a debug build fo...
I have an idea for a new social-networking experience and now need a skilled Android developer to bring it to market. The concept and basic user flows are already sketched; your role is to translate them into a smooth, modern Android application that can scale. You will design the app’s architecture, craft an intuitive Material Design interface, and connect everything to a reliable back-end (Firebase is fine, but I’m open to alternatives you can justify). Expect standard social features such as secure sign-up/login, profile creation, a real-time feed, messaging or comments, image upload, and push notifications. Performance, clean code, and thoughtful UX are priorities. Deliverables I’ll review for acceptance: • Complete, well-documented Kotlin/Java source code &b...
I am looking for a developer to create a custom IPTV/media player application called Fleezy Player for Amazon Fire Stick, Fire TV, Android TV, Google TV, and similar Android-based TV devices. I am open to an existing IPTV player codebase, template, white-label solution, or previously developed application if it already works very well. The app does NOT need to be built completely from scratch. My priority is getting a stable, professional IPTV player that works properly on Fire Stick and Android TV, supports Xtream-compatible accounts, and can be customized with Fleezy Player branding. The finished application should be delivered as an APK that customers can install directly, including through the Downloader app on Fire Stick. BASIC USER FLOW Customer installs Fleezy Player → O...

I need a single Android application that brings three abilities together: • show the live HD feed from my existing IP cameras, • let me start / stop recording that feed and push the resulting files straight to my server, and • allow me to toggle an IP-based IoT switch from inside the same interface. A simple email-password login gate is required before anyone can use any feature. Once authenticated the user lands on a dashboard where the camera stream appears immediately; from there a record button begins saving footage and silently transfers it to my server (I will give you the endpoint and credentials). A separate tab or overlay houses the IoT switch with instant on/off feedback. I am open to whichever libraries you prefer—ExoPlayer, VLC, ONVIF, RTSP, MQTT, HT...

I need a native Android application whose sole purpose is to help users work smarter and stay organised. The app will be positioned squarely as a productivity tool, so every screen, interaction and workflow should reinforce speed, clarity and ease of use on mobile. I have not finalised a feature list yet and I welcome your input, but I expect the core build to demonstrate typical productivity capabilities (for example: creating and tracking tasks, setting reminders, logging notes or anything you believe will boost day-to-day efficiency). Clean Material-design styling, smooth performance on recent Android versions and sensible local data storage are non-negotiable. If you can architect the project so that future integrations—such as Google Workspace or Microsoft Office—can be a...
I’m looking for a clean, lightweight Android application whose sole purpose right now is to control my ESP32-based hardware. The interaction must be through on-screen buttons only—no sliders or voice commands at this stage. Tapping a button on the phone should send an immediate command to the ESP32 so the device reacts with minimal latency. I already have the firmware running on the board; what I need from you is the Android side: screen layout, reliable connection logic, and simple feedback to confirm each command was sent. I’m open to whichever transport layer you feel is most robust with the ESP32 (classic Bluetooth, BLE, Wi-Fi sockets, HTTP requests, etc.); just outline your choice and why. Data monitoring and alert notifications aren’t required now but I&rsq...
I want to launch a full on-demand delivery platform on Android, with two distinct experiences: one app for customers to place and follow their orders, and another for drivers to accept jobs and navigate their routes. Live order tracking must be rendered on Google Maps in real time, and every key stage—pickup, en-route, drop-off—should trigger an email notification to the customer. Reliability is critical. Location updates need to be accurate but battery-friendly, so please factor in smart polling, foreground services, or any other best-practice techniques you normally apply. The backend has to scale smoothly under real transaction load; I will share my operating model so you can size the concurrency, database writes, and messaging throughput. Whichever stack you propose, I exp...

I am building a simple yet polished Android application that lets users book time with a “rental boyfriend” right from their phones. The first release is deliberately slim: the core flow should take a customer from selecting a package, through a secure checkout, to a confirmation screen—no social features or in-app chat at this stage. What I need from you is an Android-native build (Kotlin or Java) with fully tested payment integration. I am open to Stripe, Razorpay, PayPal, or another gateway you prefer, as long as it supports one-time charges and handles common payment errors gracefully. A clean, intuitive UI, basic booking logic, and a small admin settings area for toggling prices or availability will round out the MVP. To wrap things up smoothly, please provide:...
I’m looking for a developer to create an automation/controller system for managing multiple accounts and coordinating with an existing application. The system should handle the workflow between different accounts automatically with minimal manual intervention.

I’ll explain the exact workflow and requirements privately to interested developers. Please let me know if you have experience with automation, account/session management, and Excel/CSV integration. 30$ Budget
