Custom PCB design and embedded firmware for IoT and industrial products
I engineer IoT products from prototype to production—hardware, firmware, and cloud in one package. Specializing in custom PCB design (2-8 layers), ESP32/STM32/PIC/Jetson/Arduino firmware (C/C++), and IoT integration (MQTT, ThingsBoard, AWS and many more). I handle power supply design 12-220-440V, motor control, RS485/Modbus, and manufacturing optimization. What you get: Production-ready designs, complete documentation, and systematic problem-solving when hardware fails . I've helped startups launch products and companies retrofit connectivity to existing devices.
