Summary
🤩
Rockstar🎓
Top SchoolJakub Rzeszutko is an experienced embedded software engineer with 8 years in firmware and IoT development, currently building systems at Verkada after roles at Lime, Nordic Semiconductor and Uber. He combines low-level C/C++ and ARM microcontroller expertise with system-level tooling—creating drivers, unit-test frameworks, CI integrations and Buildroot-based Linux images—and has led SDK teams and Scrum processes. Notable open-source contributions to the widely used Zephyr RTOS improved shell robustness, added human-readable uptime and fixed subtle memory-corruption bugs, reflecting his focus on reliability and developer ergonomics. His background spans project management and hardware design, and he pairs a PhD-level electrical engineering education with hands-on PCB, driver and protocol experience. Outside work he’s a Brazilian Jiu-Jitsu purple belt, a discipline that hints at his methodical approach to problem solving and team coaching.
