Summary
🤩
Rockstar🎓
Top SchoolJakub Żymełka is a Senior R&D Engineer specializing in embedded systems with deep hands-on experience in microcontroller firmware (AVR, STM32, PIC, dsPIC) and extensive C/C++ development—over three years in Qt/QML for Embedded Linux. He combines firmware and hardware expertise, designing analog/digital electronics and PCBs using Altium and Expedition, and preparing technical documentation with LaTeX. At Nordic Semiconductor he contributes to well-known open-source projects like Zephyr and nRF Connect SDK, adding board support, device-tree and eGPIO/IPC improvements that reflect production-grade IoT experience. He is fluent with Buildroot and Embedded Linux tooling, comfortable writing Bash/Shell scripts to automate build and integration tasks. Prior roles at Aptiv and Prevac demonstrate a track record of moving prototypes into robust automotive and industrial products. Colleagues value him for bridging low-level driver work with higher-level GUI and system integration—an engineer who ships both silicon-near code and polished device interfaces.
