I’m building and iterating on a suite of web applications and want every line of code to move fast without sacrificing quality. You’ll jump straight into a modern stack where Python handles the heavy lifting on the back end and JavaScript drives interactive front-end experiences. Day to day you’ll design new features, refactor legacy pieces, write and debug code, and resolve production issues as they surface. The twist—and where you’ll really shine—is how comfortably you weave AI into that workflow. I already rely on GitHub Copilot for rapid scaffolding and on OpenAI GPT-3 for tasks such as test generation, documentation drafts, and quick proof-of-concept scripts. You should be just as fluent, knowing when these tools speed things up and when they nee...

I’m preparing to build a truly end-to-end artificial intelligence solution and I need a partner who can help me “design everything.” My vision spans the full AI stack—from data pipelines and model architecture to the visual identity the user will see—so I’m looking for someone comfortable wearing both the engineer’s and the designer’s hat. AI scope • Primary goal: a robust artificial-intelligence-driven product capable of data analysis, task automation, and predictive insight generation. • Area of focus: designing every layer of the solution, whether that means a classic machine-learning model, a natural-language component, computer-vision capabilities, or a thoughtful blend of all three. Python, TensorFlow/PyTorch, scikit-lear...

I need a production-ready Android application that scans printed lottery or gaming tickets—typically coming from an 80 mm kiosk printer—and instantly tells the user whether the monetary amount written in digits matches the amount spelled out in words. I’m building this under the name “Loterie Ticket Scanner,” and every line of code must live in my GitHub repository `loterie-ticket-scanner`. Core flow 1. The user points any supported Android camera at the ticket. 2. Google ML Kit OCR (Text Recognition v2) captures both number and text fields in a single pass. 3. Kotlin code parses the two values, normalises currency symbols and separators, and performs an exact comparison. 4. If the values match, the screen shows a clear green confirmation; if they dif...

I’m building a desktop-first retrieval-augmented generation (RAG) tool and I need a senior Python engineer to take full ownership of the document-ingestion layer. The current prototype already embeds and queries local language models, but the pipeline that feeds them is still thin. Your focus will be to ingest and normalise three document types—plain text, PDFs, and Word files—so they can be chunked, vectorised, and indexed reliably. Here is the landscape you’ll be stepping into: • Stack: Python 3.11, LangChain, FastAPI, SQLite for local mode, Postgres in the cloud, Git for workflow, and a mix of GGUF local models plus an OpenAI fallback. • Environment: Windows is the primary target, so you should be comfortable with PyInstaller or similar packaging to...

The goal is to create a separate version of the product under a new name while preserving the existing experience. No new features or design changes are required at this stage. Every screen, interaction, piece of content, backend function, and supported workflow should operate correctly acr...

I need an application that reads incoming emails, pulls the requested numbers from my data source, and sends back a clear, professional reply without my involvement. The focus is strictly on automating email responses; later on I may explore data-entry or report-generation features, but the initial milestone is all about accurate, context-aware replies. Scenario Stakeholders write asking for KPIs, month-over-month variances, or other numeric summaries stored in a Google Sheet (CSV or a small SQL table is fine, too). The system must: • detect the intent of the message, • locate and calculate the right figures, • draft a human-sounding answer that inserts those numbers, and • push the reply through Gmail or Outlook via API. Core requirements • Natural-l...

I have a small batch of Viber voice messages—fewer than ten—that I can no longer reach because Viber has cleared them to free up storage. Your job is to locate those files in the Viber backup or on-device storage, extract them without loss, and convert each one to a single, clearly audible MP3. Security is critical: I’ll provide temporary access, and I expect you to work on a local, offline environment, keep logs minimal, and delete every copy once I confirm receipt. Let me know the method you normally use (e.g., SQLite browsing, Viber desktop cache extraction, mobile root/Jailbreak with ADB/iTunes, etc.) and how you keep user data private. Deliverables • Up to 10 recovered voice messages in MP3 format • Brief note on the extraction steps you took so I c...

I already have a working Android Studio project and I’m ready to improve it in two areas: 1. Login flow • Replace the current entry screen with a fresh login page that includes a country picker dropdown showing the national flags for Lesotho (+266), South Africa (+27), Eswatini (+268), Tanzania (+255) and Uganda (+256). • When a user taps a country, its dial code must fill the phone-number field automatically. • The screen has to be fully coded in Java or Kotlin—no static mock-ups. 2. In-app shop • Beyond login, I need a product-based shop featuring unlimited item listings, a cart and a checkout flow. Think of a clean catalogue view, add-to-cart button, quantity updates and an order summary screen. Deliverables • Updated And...

Project title: Independent human code review of a Node/React/Postgres web app (auth, permissions, API, data layer) Skills: Node.js, Express, PostgreSQL, React, Security Review, Code Review Description I’m looking for an experienced software engineer to do an independent review of a web application before it goes live with its first real users. This is a quality review of the critical paths. It is not a security pen test or a certification. AI reviews are already done. I need a human. The codebase has already been through a series of AI-assisted, read-only reviews covering structure, security, maintainability, database, performance, and UI. Those findings are being worked through. What I need now is an experienced human engineer’s judgment: confirm what matters, catch what auto...

I have a Windows-only desktop tool to build and need a skilled coder who is comfortable working in either Python or Java. The core logic is already mapped out; what I’m missing is clean, well-structured code, a straightforward GUI, and an installer so the program can be run easily on Windows 10 and 11 machines without additional configuration. Here is what I will provide: • A written feature specification with workflow diagrams • Sample data and edge-case scenarios for testing • UI wireframes (basic layout, colours, and font guidelines) What I expect from you: • Source code written in Python (Tkinter, PyQt, or similar) or Java (Swing or JavaFX) – your choice, as long as it matches the spec and runs smoothly on Windows • A compiled executable (.e...

I need an Android service that hardens my phones and tablets by tying their safety to a Samsung Watch. Core workflow • While the watch is paired and within 50 m (GPS), the device behaves normally. • If the watch travels beyond that radius, a countdown starts (length to be parameterised in settings). When the timer expires, the handset performs a full factory reset. • The same timer-then-reset sequence is triggered whenever the watch is powered off or its Bluetooth connection is deliberately severed. • A unique, user-set PIN must be entered on the system lock screen to cancel the reset once it has begun. No PIN, no mercy—reset proceeds. Technical notes • Must run on Android 10 and above without root. • Should recognise any Samsung Watch that...

I want to build a brand-new social media application exclusively for Android. The goal is to launch a functional prototype that lets users create accounts, post content, interact through likes and comments, and receive real-time push notifications. I need a developer who can handle the full Android stack—from designing clean, Material-styled screens to writing well-structured Kotlin/Java code and integrating a scalable backend (Firebase, Supabase, or a solution you recommend). Key expectations • Account creation and secure login (email, Google, or phone) • User profiles with editable bio and avatar • Infinite scrolling feed for text, photo, and short-video posts • Like, comment, and follow mechanics • Push notifications for follows, likes, and commen...

My Aspera handset is stuck behind Google’s Factory Reset Protection after I forgot the screen PIN and lost access to the registered Gmail account. I haven’t tried any technical work-arounds yet, so the phone is still exactly as it was when the FRP screen appeared. The warranty period has already expired, but I can supply a scanned proof of purchase to demonstrate legitimate ownership. I want the lock lifted so the phone powers on normally and lets me register a fresh Google account. Whether you achieve that through ADB commands, SP Flash Tool, custom recovery, or another proven Android service method is up to you; I only need a safe solution that won’t hard-brick the device. Acceptance criteria – once you say the job is complete I will: • boot the phone wit...

I have a batch of PDFs that contain only plain-text content. Every word from every page needs to land neatly in a single SQL table—no images, no form fields, just raw text. Here is what the finished job looks like to me: • A script (Python, Java, or similar) that reads each PDF, pulls out the complete text, and writes it into a table such as `pdf_text` with columns like `id`, `file_name`, `page_number`, and `text_block`. • A SQL file that creates this table and lets me recreate it easily on MySQL or PostgreSQL. • Clear instructions so I can rerun the process whenever new PDFs arrive. Accuracy is critical: the stored text must perfectly match the source PDF, page by page. If you prefer libraries such as PyPDF2, PDFMiner, Tika, or pdftotext, feel free—as l...

We are looking for an experienced Data Acquisition Specialist or Codebase Broker to source high-quality, production-grade private codebases at scale for AI training data pipelines. This role focuses on identifying, vetting, and securing non-exclusive sub-licensing rights for real-world software repositories across modern tech stacks (e.g., Python, Rust, C++, TypeScript, Go, Java). Key Responsibilities Large-Scale Repository Sourcing: Identify and onboard developers, indie hackers, or engineering teams willing to license non-exclusive rights to their production-grade codebases. Rights & Provenance Verification: Verify that all codebases have 100% clean IP rights, authentic Git commit histories, and proper authorization agreements from original copyright holders.

I need a Telegram bot that monitors appointment availability at the Slovak Foreign Police and alerts users when new slots appear. Users book appointments themselves through the official website. First, verify whether reliable monitoring is possible through a publicly accessible or permitted method. If feasible, create a working proof of concept for one office and appointment category. Explain any restrictions before development. The bot should allow users to select an office and category, enable or disable alerts, and receive notifications with the available date, time, office, and official booking link. Requirements: * Prevent duplicate notifications. * Log errors and alert the administrator about repeated failures. * Allow monitoring to be paused, restarted, and configured. * Run con...

I need a lightweight Android-only solution that can sit on a phone or emulator and reliably cycle through roughly 1,000 video ads every day with no manual input once it is started. The sole function for this first release is Automated ad watching; I do not need user log-in screens or earnings dashboards right now—just press start and let it run. Core requirements • Launch, fetch, and play ads in continuous succession, meeting each ad network’s minimum “viewed” time so every impression is counted. • Handle common edge cases automatically (timeouts, network hiccups, pop-ups, orientation changes). • Keep the device awake and the service alive even when the screen is off or another app is foregrounded. • Provide a simple status readout so I ...

I’m building an AI-driven application whose core is a natural-language chatbot available both in the browser and as an Android app. I already have the product vision; what I need now is an engineer who can take it end-to-end—database, server logic, model integration, and polished interfaces—so users can converse seamlessly across platforms. The work centres on natural language processing, so you should be comfortable selecting or fine-tuning models, orchestrating inference, and exposing clean endpoints that a modern front end can call. Expect to set up the web client (React, Vue, or similar), craft a lightweight Android counterpart (native Kotlin or a robust cross-platform stack such as Flutter or React Native), and wire both to the same backend and database. Key delive...

I’ve been assigned a tricky maintenance ticket in our Spring MVC / Spring Boot code-base and, as someone still ramping up on Java, I’m stuck tracking down logical errors that sit squarely in the service layer—the part where our business logic lives. The symptoms: data flows in correctly from the controllers and persists fine through the repositories, yet the results returned to the UI are wrong. Unit tests covering the affected services either fail or pass with unexpected values, so I need a fresh pair of expert eyes to walk through the code with me, isolate the faulty branches, and refactor or rewrite the logic so every scenario behaves as intended. What I’ll provide • I can share my screen and follow the steps suggested by you. I can’t provide yo...

I want to bring a Five-Nights-at-Freddy’s atmosphere to Roblox while keeping the core gameplay firmly incremental. Players will start small and, through steady progression, unlock systems, rooms, and mechanics until they are running a fully functioning facility—all inside a tense, animatronic-haunted setting. The project’s main goal is simple: deliver a full, working game that feels just as satisfying to grow as it is unsettling to survive. Gameplay type: incremental Primary focus: building the entire experience from the ground up rather than just a single mechanic Mode: multiplayer—data must replicate correctly across servers, and progress must save between sessions. You’ll work in Roblox Studio with Lua, creating everything from resource generators and...
