About me
I’m Theo Johnson, a PCB designer with over 9 years of experience helping clients turn complex electronics ideas into reliable, production-ready designs. If you’re struggling with signal integrity, RF impedance, high-current routing, power supply stability, or embedded hardware and firmware, I can help. I design RF, IoT, STM32, ESP32/ESP8266, SMPS, DC-DC, MPPT, inverter and BMS PCBs with Altium Designer, KiCad and EasyEDA, delivering clean layouts, practical engineering and clear documentation. My goal is to reduce risks, solve challenges and deliver hardware ready for manufacturing.
