Phan Thanh Toan

Senior Embedded Hardware Engineer with 5+ years of experience delivering industrial IoT systems — from schematic design and multi-layer PCB layout through SMT coordination, field deployment, and post-deployment troubleshooting. I have directly designed a wide range of complex boards: Ethernet Switch board (Realtek), PLC IoT board (STM32), AGV control board, Quectel SC20 carrier board, and E-foil wireless remote controller (ESC) . My strength is taking hardware from prototype to deployable product: board bring-up, DFM review before SMT, building embedded Linux systems on Quectel SC20 and Raspberry Pi, developing firmware on ESP32 and STM32, and integrating industrial systems via Node-RED, PLC, Modbus, and MQTT. I don't just make hardware work — I make sure it works reliably in the field, and I document everything so the next version doesn't repeat the same problem.
