Senior🎓
Top SchoolPatrick Huesmann is a Senior Software Engineer based in Hamburg with 20 years of experience building embedded Linux and bare-metal firmware for sensors, industrial control and high-performance experimental computing. He has led small teams and owned end-to-end stacks—from bootloaders and Yocto-based Linux systems to DSP algorithms, web frontends and hardware bring-up—at companies like Kongsberg Maritime and DESY. Patrick’s work spans chemical and CO₂ sensing, OPC UA monitoring frameworks, and real-time data loggers, reflecting deep domain expertise in measurement systems and signal postprocessing. An active open-source contributor, he has improved Arm Cortex-M debugging and SWV tooling in the well-used pyOCD project, enhancing device compatibility and developer workflow. His background in technical physics informs a rigorous, measurement-driven approach to firmware and algorithm design. Colleagues rely on him for pragmatic debugging skills and for translating complex hardware constraints into reliable embedded software.
