Summary
👤
Senior🎓
Top SchoolSzczepan Zalega is a Linux embedded software engineer with 10+ years of hands-on experience building secure firmware, cross-platform GUIs, and tooling for production devices. He has led technical efforts at Nitrokey—managing product lifecycles, designing test and flashing infrastructure, and proposing the Nitrokey Webcrypt standard—and contributed security-critical fixes to the popular Solo 1 FIDO2 firmware. Proficient in Rust, C/C++, Python and TypeScript, he blends low-level embedded work (bootloaders, CTAP fixes, OpenCL GPGPU object detection) with full-stack and NLP experience from earlier roles. Based in Warsaw, he pairs practical QA and security review discipline with a track record of open-source collaboration and reproducible manufacturing tooling. Notably, he has built LLMs and managed their data pipelines, an uncommon cross-over for an embedded specialist.
