About me
Build electronics that work reliably from the first design. I specialize in PCB layout, circuit design, multilayer boards, simulation, and embedded systems (ESP32, Arduino, IoT). I help startups, engineers, and developers turn ideas into production-ready hardware with clean schematics, optimized routing, and stable performance. My focus is on reducing design errors, improving manufacturability, and delivering clear, structured outputs. Message me to review your project before ordering.... Read more
