Summary
🤩
Rockstar🎓
Top SchoolPiotr Krzyzanowski is a Senior R&D Engineer based in Lower Silesia, Poland, with a crossover career in hardware, firmware and embedded software spanning startups and large telecom and semiconductor firms. He co-founded Auxilia Technology and now contributes to Nordic Semiconductor’s R&D, applying hands-on expertise in driver testing, benchmarking and peripheral performance for the widely used nRF Connect SDK. Earlier roles at Nokia and Agilent underpin a strong background in hardware integration, verification and electronic engineering, informed by a Master’s in Electronics and Telecommunication from Wroclaw University of Technology. Piotr’s open-source contributions focus on practical test cases and power/multicore benchmarks for drivers like PWM and QDEC, demonstrating a bias for measurable performance and testability improvements. Comfortable across the full embedded stack, he blends entrepreneurial initiative with rigorous systems-level validation—often optimizing low-level features like LED and clock control to surface real-world device behavior.
