Job Summary: In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters. You'll create realistic, interesting and challenging coding tasks for AI to solve involving feature implementation and bug fixes, and implement deterministic verifiers that accept reasonable valid solutions and reject everything else. What we're looking for Strong backend experience in Java, Node.js, Go, Rust, Typescript, Python, C++ or similar A track record building scalable services and APIs Comfort with debugging, performance work and automated testing Solid code review instincts A stro...

My production backend, built with Node.js and Express, has begun throwing API-level errors whenever it calls certain third-party services. I need someone who can dive into the existing SQL-based data layer, trace the root cause, and then patch or rewrite the integration logic so responses return cleanly and consistently. The work will involve tracing stack traces, profiling slow SQL queries that may be compounding the issue, refreshing outdated code that interacts with external APIs, and writing automated tests to confirm nothing else breaks once the fixes go live. You are free to recommend better patterns, libraries, or small architectural tweaks as long as they stay compatible with the current stack. Because the exact scope may expand once we uncover hidden bugs, I’m open to eith...

My WordPress site throws the message: “Composer detected issues in your platform: Your Composer dependencies require a PHP version >= 8.3.0”. At the moment I don’t even know which PHP version the server is running, and I’m not sure whether any particular plugin or theme is behind the problem. What I need is a clean, end-to-end fix that gets both the public site and the WordPress admin area working normally again. Here’s how I see the job: • Pinpoint the current server PHP version and, if it’s below 8.3, upgrade or adjust the hosting settings so that Composer stops complaining. • Audit core WordPress files, active plugins, and the theme for compatibility with PHP 8.3+. • Resolve any conflicts you uncover—this could involv...

I’ve built three informational business sites with Base44 and now need a sharp set of eyes—and hands—to make them launch-ready. Every page, button, link and asset must function flawlessly. That includes our contact forms, the embedded interactive maps and the customer login area. Here’s what I expect: • Diagnose and eliminate front-end and console errors, broken links, mis-routed buttons or missing assets. • Verify the contact forms deliver messages to the correct address and show success/error feedback. • Check that interactive maps load quickly and pin locations accurately. • Log in and out of the customer area, confirming credentials, password reset and session handling all behave as intended. • Run cross-browser and mobile r...

I want to see whether a small piece of my current WinOLS workflow can be automated before we commit to a larger roll-out. You will log in to my Windows PC where WinOLS 5.93 with OLS530 is already installed, pick one agreed-upon operation, and script or macro it end-to-end using a single original ECU file and its matched donor/reference project. When the routine runs I should receive the same output I would obtain if I performed the task manually in WinOLS, including correct offset handling and checksum availability. Deliverables • A working proof-of-concept that performs the chosen operation automatically on the supplied files • A short report summarising the test result, any caveats you discovered, and where future limitations might appear No web integration or full mult...

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 have a custom board built around the STM32G031 and I want a clean, production-ready firmware project created in C with STM32CubeIDE. Your first task is to bring the microcontroller to life: set up the system clock, configure the required GPIO pins, verify the build, and program the device. Here is the scope I need covered: • Create a CubeIDE project that targets STM32G031, using either HAL or direct LL drivers where it makes sense. • Configure clock tree (HSE, HSI or internal PLL as required) so the MCU runs at the specified operating frequency. • Initialise all GPIOs I mark on the schematic; direction, speed and pull settings must match the hardware design. • Build, generate the .hex/.bin files and flash them onto the board through ST-Link over SWD. • ...

I’m building a compact control panel that combines an ESP32 core, a membrane keypad, and a 3.5-inch TFT LCD. I already have functional requirements and rough block diagrams; what I now need is the full electronic design, ready for manufacturing. Scope • Power architecture: single regulated 5 V input with the necessary step-downs and filtration for the ESP32’s 3 V3 rail, back-light drive, and any aux lines. • Digital section: ESP32 module or bare chip with all pins broken out for firmware flashing, reset, and debugging. • Interfaces: matrix keypad connector and ESD protection, 8/16-bit TFT LCD interface, plus level-shifting where required. • Communications: I²C, SPI, and UART brought to headers for external sensors and future expansion. •...

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 sharpen my day-to-day troubleshooting skills around Twilio Programmable Voice and, in particular, dive deep into TwiML and call-flow logic. The goal is to meet regularly—live, one-on-one—to dissect real customer-reported issues, replay them with sanitized data, and step through practical fixes. Topics that matter most to me include: building and debugging TwiML, shaping call flows, handling webhooks, analysing Voice Insights, and interpreting SIP-level problems such as latency, jitter, and packet loss. I already work in technical support, so the sessions should feel like an advanced lab where we pull log files, test APIs, and reason through what is really happening on a call. This is ongoing mentorship rather than a packaged course. We can agree on a cadence a...
