I am a freelance hardware and firmware developer. By taking care of both hardware and firmware in a design, I ensure that both hardware and firmware are optimized for each other, resulting in a better product.
- schematics and PCB design, using KiCAD
- STM32, ESP32, and others
- I2C sensors, memories and others
- SPI devices, eg. e-paper displays
- each design has a CI/CD style workflow, taking care of automatic testing, BOM production and validation, etc.
- bare metal & Zephyr
- STM32, ESP32, ARM
- C++
- Test-Driven Design Methodology (TDD)
