About me
I help startups, makers, and product teams turn electronics concepts into reliable, manufacturing-ready products. My expertise covers PCB design, PCB layout, circuit schematic, KiCad, ESP32, STM32, BLE, sensor IoT PCB, power electronics, reverse engineering, PCB review, and optimization. I also create custom IoT enclosures, PCB cases, electronics housings, and smart home device enclosures with 3D CAD, component fitting, mounting features, and DFM. From schematic to enclosure, Gerber files, BOM, and prototype-ready CAD, I focus on clear communication, precise work, and production-ready results.... Read more
