Top-Rated Embedded Engineer, 40+ projects shipped. I build STM32/ESP32 firmware, PCB designs, and custom PySide6/Qt desktop tools that turn hardware concepts into products. Most hardware projects stall in the gap between the silicon and the software that has to drive it. That's exactly where I work, I take a project from schematic and PCB layout, through low-level firmware, all the way to the desktop application your team uses to configure, test, and visualize the system. What I build: • Firmware & embedded C/C++ - STM32 and ESP32 development, from bare-metal drivers to production firmware, with hardware bring-up and debugging. • Hardware & PCB - DFM-ready schematic capture and PCB layout in Altium and KiCAD, designed alongside the firmware so the two actually fit. • Desktop tools & GUIs - Native PySide6 / PyQt / C++ applications purpose-built for hardware interfacing, instrument control, data visualization, and automated test. • Automation & reliability - Self-hosted n8n pipelines with custom Python/JavaScript, plus CI/CD, Git, and automated unit testing across C and Python codebases. Because I own both sides - the hardware and the software that controls it, you don't have to coordinate two contractors who blame each other when something doesn't talk. You get one engineer accountable for a working, production-ready system. If you've got an embedded product, a test rig, or a hardware-control tool that needs building, send me the details and I'll tell you straight whether it's a fit and how I'd approach it.
