Vladimir M.

I'm a senior software engineer working across the full stack: microcontroller firmware, desktop applications, mobile apps, backends and the integrations that connect them. Clients usually come to me with projects that are complex, unfinished or stuck, and I take them through to a working result. "Vladimir delivers solutions quickly and with 100% accuracy." (client review) Recent work for clients: - Automotive firmware: reverse engineered and extended the firmware of an ARM Cortex controller, from decompilation to new features and testing on the vehicle. - Embedded systems: a Raspberry Pi device that emulates a USB plotter to capture data from industrial equipment; ESP32 firmware and system design. - Desktop C++: CloudCompare plugins (3D point clouds); DNS-SD service discovery for a C++ IPP print server. - Mobile: a Flutter step-tracking app for Android, delivered on schedule and rated 5 stars. - Backend and cloud: refactored a FastAPI application and deployed it to AWS Lambda; Python data-loading tools. - AI: reduced response time and API usage for an AI English tutor. - Web and automation: a browser-based room correction audio app, trading automation, Telegram bots, system-wide proxy tunneling. Technologies: C, C++, C#, Python, Dart/Flutter, JavaScript; ESP32, STM32 (ARM Cortex-M), Raspberry Pi, Arduino; Qt, Windows, Linux; FastAPI, Laravel, REST, WebSocket, AWS; Telegram Bot API, payment gateways, LLM APIs. How I work: - I review the requirements first, ask the questions that matter and give you a clear plan with a fixed estimate. - You get regular progress updates and same-day replies. - The code is clean and documented, and I hand it over properly so it can be maintained after the project. - If something turns out to be impossible or more expensive than planned, I tell you early, before you pay for it. If your project needs someone who can handle both the hardware and the software side, send me the details and I'll give you an honest assessment of what it takes.
