PCB ENGINEERING | Embedded Systems | RF Solutions | Microcontroller Firmware Development

I'll help you bring your electronic project from concept to a fully functional prototype, ready for production. I build complete PCB boards featuring microcontrollers (ESP32, ESP8266, STM32, ATmega), power supply circuits, battery management and charging circuits, sensors, actuators, connectors, antennas, and RF components.

I guide stack-up selection to minimize signal integrity and EMI issues, write basic firmware for board testing, and help you select the right electronic components based on budget and market availability. You'll receive all files needed for PCB production.
