Summary
🤩
Rockstar🎓
Top SchoolKamil Piszczek is a firmware engineer with a decade of experience building low-level Bluetooth, NFC and IoT systems, currently contributing at Nordic Semiconductor and to the Zephyr Project. He specializes in secure Bluetooth stacks and NFC driver development—having implemented NFC drivers for the nRFx package and advanced NFC Type 2/4 tag support—and regularly authors tests and fixes that harden privacy and address-resolution behavior in Zephyr’s Bluetooth code. Kamil has led interoperability testing platforms at Bluetooth SIG UnPlugFests and briefly served as a team lead, combining hands-on development with practical leadership in embedded QA. His background in automatic control and robotics (MSc/BS from AGH) underpins a systems-minded approach to firmware design and hardware integration. An active open-source contributor, he has added security, persistent storage and authorization APIs to widely used projects, showing a knack for improving both functionality and testability. Outside typical firmware work, he pursued Ethereum developer certification, signaling curiosity about decentralized systems beyond embedded domains.

zephyrproject-rtos/zephyr
Jun 2018 - Feb 2025
Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:190 reviews, 66 PRs, 466 comments in 6 years 8 months
Contributions summary:Kamil primarily contributes to the Zephyr RTOS project by developing and testing Bluetooth functionality, specifically focusing on the security and privacy aspects within the Bluetooth stack. Their work involves writing BabbleSim tests to validate RPA (Resolvable Private Address) behavior and address conversion during identity resolution, addressing issues related to connection address handling and configuration. The user also improves settings handling and fixes an RPA initialization issue for non-default Bluetooth identities and enhances the existing testing framework. Furthermore, the user adds a new authorization callback API to handle and validate GATT operations.
