Shawn C.

A Senior IoT Engineer with a strong focus on end-to-end embedded systems and hardware design, from concept to production.

My core strength is in PCB/EDA design (Altium Designer, EasyEDA), combined with practical experience building real-world IoT devices that have to work reliably outside of lab conditions. I’ve designed systems involving power management, sensor integration, wireless communication (BLE, Wi-Fi, cellular), and low-power optimization.

I regularly work on:

Custom PCB design (schematic, layout, Gerbers, BOM)

Embedded systems using ESP32, STM32, and similar MCUs

Power electronics (buck/boost, battery systems, USB-C, thermal considerations)

Communication protocols (BLE GATT, I2C, SPI, UART, Modbus)

Debugging and improving existing hardware (thermal issues, noise, stability)

I’ve also supported projects that required tight constraints—small form factor boards, battery-powered systems, and harsh environment designs—where reliability and efficiency matter more than just “making it work.”

Beyond hardware, I understand the full IoT stack and can align firmware, hardware, and system behavior to ensure everything works together cleanly.

If you already have a design, I can help refine and fix it. If you’re starting from scratch, I can take it from idea to a production-ready board.
