I have a batch of Android tablets that refuse to complete their normal software update because I can no longer sign in to start the process. I need a freelancer who can walk me through—or remotely carry out—a full software update so each device is running the latest version it supports and all security patches are applied. The work will be finished once every tablet can: • sign in without errors • download and install the current official system update • reboot and operate normally afterward If you have proven experience recovering locked-out devices and pushing OS or firmware updates, I’m ready to get started right away.
I’m looking for a fully-automated trading bot that operates on Polymarket and follows a clear trend-following strategy. The core requirement is that once the bot is live it can open, manage, and close positions without manual intervention, reacting to price trends in real time. You’re free to choose the programming language and tech stack, provided the final solution is reliable and easy for me to run on a VPS. A straightforward configuration file or dashboard that lets me adjust risk parameters and market filters would be ideal. Robust error handling and basic logging are a must so I can monitor performance and diagnose issues quickly. Because I need this finished within a month, I’ll appreciate a concise development roadmap, quick progress check-ins, and well-commente...

I have an Android build that is feature-complete and ready for a final quality sweep before it hits the Play Store. What I need from you is twofold: 1. Manual validation • Run my full functional pass and documented edge-case matrix across a healthy mix of real Android devices and OS versions (no emulators for this stage). • Log every deviation from the acceptance criteria with crystal-clear steps to reproduce, screenshots or screen-captures, device/OS details, and any relevant logs so my devs can fix fast. 2. Automated regression coverage • Build an Appium-based suite that focuses on the critical user flows I will share. • The suite must be reliable enough to drop straight into our CI pipeline (GitHub Actions today, but a simple shell entry point i...
I run several AI initiatives that revolve around computer-vision pipelines, and I need an adaptable hand to keep our image data in perfect shape before it ever touches a model. Your main focus will be classic machine-learning groundwork: pulling raw image assets from cloud storage, auditing their quality, handling augmentations, labeling inconsistencies, and packaging everything into tidy, well-documented datasets that flow straight into our training scripts. Most tasks live in the data-preprocessing and cleaning stage, so you should be comfortable writing reproducible code for resizing, normalization, class-balancing, and automated sanity checks. We currently use Python with Pandas, NumPy, OpenCV, and sometimes Albumentations; if you have a favorite toolkit that speeds things up, I am op...
I want to turn the quirky idea of a “Chicken Road Prediction Bot” into a fully working Android app. The concept is simple: feed the app either live video or pre-recorded movement data of chickens near a roadway and have it predict if, when, and where a bird will step onto the road. The platform is strictly mobile and Android is the only operating system I need supported. Here’s what I expect: • A lightweight Android application (Kotlin or Java) with a clean UI that shows a camera preview or data feed and overlays the real-time prediction. • An on-device model—TensorFlow Lite, PyTorch Mobile, or a comparable framework—that can run offline and outputs a confidence score plus an ETA for the crossing. • A simple stats panel logging every pr...

Software Developer Required – Vehicle Movement & Loading Management System We require an experienced software developer/team to develop a centralized vehicle movement and loading management application operating across three locations. Basic Workflow Vehicle Entry → Loading Point → Vehicle Exit At each location, an operator will use a device to enter/update the vehicle status. All data must be centralized and visible to an authorized controlling user. Information to be Captured At Entry: * Vehicle Registration Number * Vehicle Type * Driver Name/ID * Driver Contact/identification details, if required * Entry Date & Time (automatic) * Purpose/Load details, if required * Unique Vehicle/Transaction ID At Loading Point: * Vehicle identification * Loading status...
I’m building an application whose core value is actionable forecasts generated by AI-driven predictive analytics. The idea is to feed historical data into a well-designed pipeline, surface trends, and return clear recommendations or probabilities to end-users inside a clean interface. I have not locked the project into a single sector yet, so whether the data turns out to be time-series sensor readings, customer behaviour logs, or financial records we can choose the most suitable modelling approach together. Here’s how I picture the flow: first, you and I refine the problem statement and decide what questions the model must answer. Next comes data ingestion and cleaning, followed by feature engineering and model selection—think scikit-learn, XGBoost, TensorFlow, or which...
I'm looking for an experienced developer to enhance my existing Java Spring Boot microservices application hosted on AWS.

I need a lightweight key-logging application that runs silently on Windows and continuously captures every keystroke. The program must bundle those logs and forward them automatically to both an email address and a Telegram chat that I will specify during setup. Stability and stealth are important: the executable should start with Windows, avoid triggering Defender, and write minimal footprints to disk. Logs have to arrive in near-real time or on a schedule I can change in a simple config file. Deliverables: • A compiled Windows installer or standalone executable • A brief setup guide showing how to enter my SMTP credentials and Telegram bot token / chat ID • Source code so I can review and recompile if needed Please keep external dependencies to a minimum and...
## Job Description## Overview We are seeking an experienced, high-velocity Full-Stack Developer to build and launch an AI-driven credit intelligence and automated dispute generation platform. The architecture, database schemas, API data contracts, and deployment workflows are already fully designed and documented. We need a sharp developer who can take our structured technical blueprints and build a stable, production-ready MVP within a 30-to-45-day window. This is a clean-slate project with zero technical debt. You will be working with a lean, modern async Python stack on the backend and your choice of a clean SPA framework on the frontend. ------------------------------ ## The Technical Stack * Backend Framework: FastAPI (Python 3.11+, fully async, Pydantic v2) * Database &a...
I already have the PickCab Partner Android app live on Google Play (). I now need two additions: 1. Integrate the Razorpay payment gateway end-to-end, handling order creation, callbacks, success / failure states and error logging, then pushing a new build to internal testing so I can see live payments working. 2. Add a real-time, one-to-one text-only chat inside the app so drivers and riders can message each other. Basic features I expect are time-stamps, typing indicator and push notifications when the app is in the background. You are free to use Firebase, or any solid alternative. No extra authentication screens are necessary; the new modules should plug straight into the existing flow. Deliverables: • Updated, well-commented source code with Razorpay SDK and chat module integr...
I want to guide a small group of absolute beginners all the way to the point where they can land an entry-level role in AI, machine learning and generative AI. To get there, I’ll need a mentor who can design and deliver a complete learning journey—covering core theory just enough to ground them, then pivoting quickly into hands-on coding, model training and project work that showcases real-world skills. Here’s what I’m expecting from you: • A clear, modular curriculum that progresses from Python basics through classic machine-learning workflows and on to modern generative models (GPT-style LLMs, diffusion, etc.). • Live or recorded sessions with practical demos, Jupyter notebooks and datasets my trainees can keep experimenting with after class. •...
I need a lightweight Android application that keeps my customers instantly informed about their purchase progress. The core task is to build a stable push-notification system that fires whenever an order moves to a new status in our back-end. Each notification must be clear, timely, and triggered exactly once per status change so users never miss an update or receive duplicates. My API team will expose a simple REST endpoint returning the current order state; you can poll it or use webhooks—whichever gives the most reliable result on Android. Feel free to integrate Firebase Cloud Messaging if it speeds things up; I just need the service to scale and to handle basic fail-over scenarios. At this stage I am not asking for full real-time map tracking or a user-login module, but I would...
I want to create an Android application that works much like the Superfone IVR app, but tailored to my organisation’s customer-support workflow. The core goal is to make it effortless for callers to reach the right information or person without waiting on a human operator. Key functions I need built in: • Automatic IVR flow that greets callers and routes them through spoken menu options. • Branches that allow callers to: – get answers to common questions, – record and escalate complaints, – request detailed information that will be sent to them by SMS or email. • An intuitive dashboard where I can update the menu prompts and review call analytics. • Secure cloud storage for recordings plus the ability to download ...
I need an Android application that allows people to join real-time voice chat rooms, exchange short voice messages, and build public or private groups around shared interests. Every user should have a rich profile (avatar, bio, follower count, etc.) that is visible inside and outside rooms. Access & security Sign-in must happen exclusively through Gmail-based email login, using Google OAuth so the flow stays familiar and frictionless. No phone or other social options are required at launch, though the architecture should leave room for them later. Core feature set • Live group voice chat rooms with push-to-talk and host-controlled mic permissions • One-to-one or one-to-many voice messages that can be played back inside the room or in direct chats • Persistent u...
I have several ongoing initiatives that each require their own AI agent—some conversational, others focused on data extraction or decision support. I need someone who can take an idea, choose an appropriate framework (for example, Python with LangChain or Rasa for chat, TensorFlow or PyTorch for analysis-heavy tasks), and turn that into a production-ready microservice or packaged module. Typical flow • Review the project brief with me and translate objectives into agent capabilities • Propose the tech stack and model choice, clearly explaining trade-offs • Build, test, and fine-tune the agent, then expose it through a clean API or SDK • Hand over clear documentation and lightweight maintenance scripts (Docker or similar) Because each project differs, modul...
Android Device Service Demo APK – Xiaomi, Vivo & Oppo Description I am looking for an experienced Android developer to create a simple demo/testing APK for a mobile-device software-support business. The application will be used as a UI/workflow demonstration only. It must not perform real FRP bypass, security-lock removal, IMEI modification, or unauthorized device access. Main Requirements The APK should have a professional tool-style interface with: * Xiaomi * Vivo * Oppo * Device/service selection * Device model field * Service selection * Order/request button * Processing animation * Demo result/status * Success/failure status * Order/reference ID * Simple activity/history screen * About/support section Demo Workflow Example: Brand: Xiaomi Model: Redmi Note 13 Service...
I have a clean, ready-to-use Iris dataset and need a complete Support Vector Machine classification pipeline built around it. The job is straightforward: tune an SVM (scikit-learn or similar) to separate the three Iris species, document the process, and hand over reproducible code and results. Here’s what I expect: • A concise notebook or script that loads the data, performs any minimal preprocessing you find beneficial, runs hyper-parameter optimisation, trains the final model, and outputs accuracy, precision, recall and the confusion matrix. • A short write-up (markdown inside the notebook is fine) explaining why the chosen kernel and parameters work best, plus any insights you notice in the feature space. • Saved model file so I can deploy or reload it quickl...
I’m looking for a developer who can build a lean, production-ready Android shopping app that does one thing exceptionally well: move users from “Add to Cart” straight through a secure checkout and payment gateway. Scope • Native Android build (Java or Kotlin) that runs smoothly on the current OS versions. • Core screens: simple product view (fed by my existing API), cart summary, shipping details, payment screen, and order confirmation. • Integrated payment gateway—Stripe is preferred, but I’m open to your recommendation as long as it supports major cards and works worldwide. • Guest checkout only; no user sign-up or login flows. • Clear error handling, validation, and success/fail callbacks so I can track each order’s...
I’m building a web application and need a seasoned Java full-stack developer to work alongside me from backend through to the React UI. The help I’m after is truly end-to-end: designing or extending Java REST APIs, wiring them into responsive React components, and keeping everything clean, tested, and well-documented. You’ll jump between backend logic (Java 17, Spring Boot, JPA/Hibernate, Maven) and the React frontend depending on the task at hand, always with an eye on performance, security, and code quality. Unit and integration tests, pull-request reviews, and occasional CI/CD tweaks in GitHub Actions and Docker are part of the routine. Acceptance criteria for anything we merge are straightforward: • All automated tests pass and new code meets the existing style...

I need a web app that plugs into the Google Maps / Places API and pinpoints potential service-provider leads in any chosen area. The flow is straightforward: users enter a location or keyword, the map displays matching service businesses, and the system captures each company’s customer reviews for later analysis. The heart of the build is reliable API integration, quick filtering and a compact dashboard where I can read, sort and export the review data. Contact details or full service lists could be added later, but for this first release the reviews themselves are the single non-negotiable data point. Core deliverables • Front-end interface (React, Vue or vanilla JavaScript) that lets me search, view markers and browse reviews • Back-end service (Node, Python or simi...
I need a complete Android application that lets both riders and drivers schedule rides ahead of time. The scheduling flow is the highest priority: a rider should be able to choose pickup, destination, date, and time; a nearby driver receives the request, can accept or decline, and both parties get confirmation inside the app. Although real-time tracking and payment integration are off the critical path for this first version, the codebase should be clean and modular so those features can be bolted on later—or even ported to iOS or Web without a full rewrite. Deliverables • Production-ready Android app (APK + Play Store-ready bundle) • Full Kotlin/Java source code in a Git repo with README setup instructions • Simple backend (Firebase, Supabase, or similar) handli...
I have a fully-built mobile app in FlutterFlow that I’m now ready to take native. Your job is to reproduce the entire experience in Swift for iOS and Java for Android, matching the original design pixel-for-pixel, duplicating every feature, and retaining the same smooth performance—or improving it where possible. The current build works, but being tied to FlutterFlow limits my control over custom code and optimisation. I’ll provide the existing FlutterFlow project, Figma screens, backend endpoints, and a brief test plan so you can see what “identical” really means. Key expectations • UI/Design fidelity: layouts, colours, typography, animations, and any custom widgets must look and feel exactly the same on both native platforms. • Features &...

Inwant a image cum catalog of my real estate inventory to share to potential buyers
I need a clean, modern website that lets visitors browse my residential listings with ease. The site’s sole purpose is to showcase properties, so every page should keep photos and details front-and-center while encouraging enquiries. Key elements I must have: • Property pages with a fast-loading photo gallery • Seamless virtual-tour integration (YouTube, Matterport, or similar) • A simple contact form on each listing that sends leads straight to my inbox Please build the site to be mobile-friendly, search-engine aware, and easy for me to update with new homes later—WordPress, Webflow, or another user-friendly CMS is fine as long as the end result looks polished and loads quickly. Hand-over will include all source files, login credentials, and a short wal...
We operate as a software house and are delivering this project for one of our clients. The project is an Android application built in Flutter, designed to improve and extend the functionality of popular ride-hailing applications. We have been developing this project over the past several months, and the client is interested in continuing its development in the future. For this reason, we are looking for an individual developer or a team with whom we can establish long-term cooperation. Unfortunately, we currently do not have access to the application's original source code repository. The previous development team involved in the project has closed its business, so at this stage we only have access to the latest APK file. Based on this APK, it will be necessary to recreate the appl...
I want a complete Android chess app that feels modern and social. The board and pieces should be fully 3-D, rendered smoothly on mid-range phones, with intuitive pinch-zoom and rotate gestures so matches feel immersive rather than flat. Core gameplay centres on real-time online multiplayer. Players must be able to start a quick match against anyone worldwide or create a private room and invite friends. While a game is running, a lightweight in-app chat window should sit beneath the board so opponents can talk without switching screens. Around the games, I need a simple community layer: • Persistent friend list so users can add, remove, and directly challenge contacts. • Elo-style ranking system with leaderboards that update automatically after each rated match. Google, Faceboo...

We run a workflow-automation SaaS that lets customers build event-driven processes, route approvals, and call external services. The stack is Java 17, Spring Boot, PostgreSQL, Celery, Redis, Docker and AWS, all delivered in a fully multi-tenant environment. The immediate goal is to harden security and drive horizontal scalability without slowing feature delivery. That means: • Strengthening authentication, authorization and tenant-isolation layers • Stress-testing and tuning PostgreSQL schemas, indexes and queries for millions of tenant rows • Refining REST/JSON APIs so third-party services can plug in cleanly, with versioning and clear contracts • Profiling Spring Boot services, Celery workers and Redis caching to remove bottlenecks, then containerising improve...
Yomama Investments YOMAMA Investments is an existing single-player web prototype: a Bloomberg-style retail "terminal" wrapped around a playful economy game (buildings, production, marketplace) and a paper-trading engine. It is plain HTML/CSS/JS with no build step; all state lives in browser localStorage under one hardcoded account. The job: turn this into a working classroom prototype for ~30 high school students playing simultaneously, run by a teacher, with a two-act game loop: Act 1 — Students play the existing buildings/production/marketplace economy to earn in-game cash. This teaches earning, costs, and opportunity cost. Works as a classic idle management/economic simulation game. Act 2 —Reaching a cash or level threshold unlocks the trading floor. Students i...

I’m ready to turn my wire-frames and feature list into a real, installable mobile app that runs on both iOS and Android from a single codebase. Because my main goal is personal learning, I want every part of the project to be structured so I can study and extend it later. Framework I’m open to whichever stack will give me the most “learning and benefit.” If you’re equally comfortable with Flutter, React Native, or any modern alternative, let me know which you’d recommend and why before we start. Scope of the first release • On-device sign-up / log-in flow (email + password) • All core screens from my wire-frames (I’ll share them once we kick off) • Push notification integration and a simple test message to prove end-to-end ...
I have a small in-house codebase that already runs a few large-language-model helpers, but I now need to expand it with three new agents: a Sales Assistant, an Email Agent, and a Document Management Agent. All three must plug into the same Python stack (LangChain, OpenAI API, vector store, webhook layer) and respect our existing coding patterns. Here is the core scope we will iterate on together: • Sales Assistant Agent – Lead generation from incoming data feeds and web sources – Follow-up communication that can draft, personalise, and schedule messages – Basic sales analytics so my team can see pipeline health at a glance • Email Agent – Automated responses that pick the right template and tone – Sorting and categorisation i...
I need a straightforward Android-only application that lets me record the daily status of each customer order while I’m on the go. The core flow is simple: open the app, pick or type an Order ID, choose a status (for example Pending, Shipped, Delivered, Cancelled), add an optional note, then hit Save. I should be able to review and edit past entries just as easily. Because this will be used every day, the interface has to load fast, work smoothly on recent Android versions, and stay usable even when the device is temporarily offline—queued entries can sync once a connection returns. Feel free to recommend a light, reliable backend (SQLite, Firebase, or another option you trust); I’m flexible as long as the data is stored safely and can be exported later. Deliverables ...
I need a production-ready Android finance application that will easily clear a formal security review. I will hand over the compliance matrix, API partner documentation, and branding assets; your job is to transform them into a polished, secure app that covers: • On-boarding with KYC checks and biometric login (fingerprint / face). • Encryption at rest and end-to-end TLS in transit. • Account dashboard showing real-time balance updates with a detailed breakdown of holdings. • Searchable transaction history pulled via partner APIs. • Full audit trail—every critical user action logged immutably for future audits. The build must follow modern Android best practices (Kotlin preferred, Jetpack, MVVM, OWASP Mobile Top 10 mitigation) and ship with reproduc...
I’m building an Android-only app that lets customers browse our services, lock in an available time slot, and leave a deposit before the appointment is confirmed. I will supply the full set of business rules that define working hours, blackout dates, staff skill levels, and any custom availability logic—your job is to translate those rules into a smooth, error-free booking flow. Key functions I expect from day one: • Real-time availability based on my rules, with instant reservation once the deposit goes through. • Google Calendar two-way sync so new bookings appear on our shared calendar and any changes we make there update the app. • Push and email reminders for both the customer and our in-house team, plus automatic handling of reschedules and cancellati...
I’m building an Android-only e-commerce application and want to nail the browsing experience first. The core task is to create a smooth, responsive product-listing and search module. Shoppers must be able to explore the catalogue, type a query, and instantly refine results by ratings and reviews—you can treat that filter as mandatory. If you have a clean way to layer in other filters or even lightweight recommendations later I’m open to it, but for this milestone I only need: • Search bar with real-time suggestions • Ratings & reviews slider or toggle to narrow results • Pagination or lazy-load list so large inventories feel fast Please implement in Kotlin (Android Studio), follow modern MVVM or similar architecture, and keep the codebase rea...
