Embedded Software Engineer
Netherlands
Summary
🤩
RockstarHein Wessels is an Embedded Software Engineer based in the Netherlands with seven years of hands-on experience building firmware and device drivers for resource-constrained systems. He contributes to high-profile open-source projects like the Zephyr RTOS, where his work on ADC drivers, multi-channel support, DMA transfers, Bluetooth fixes, and shell utilities demonstrates strong low-level systems and testing discipline. Hein balances pragmatic refactoring and bug fixes with feature development, ensuring drivers are robust and maintainable in production IoT environments. Colleagues would describe him as detail-oriented and methodical, comfortable navigating hardware-software boundaries and constrained tooling. Outside work he channels the same systems-thinking into complex Factorio setups, hinting at a penchant for optimization and emergent system design.
