Rockstar🎓
Top SchoolMateusz Kapała is a firmware engineer based in Krakow with three years of hands-on experience designing embedded systems and IoT firmware. He has progressed from embedded developer to team lead at Comarch and now contributes to Nordic Semiconductor, focusing on BLE stacks, DFU, and USB/MCUboot workflows for nRF52/nRF53 platforms. An active open-source contributor to flagship projects like Zephyr and the nRF Connect SDK, he’s fixed subtle Bluetooth host bugs, added per-connection bondable features, and improved Thingy53 USB and DFU behavior—demonstrating a deep practical understanding of wireless protocols and bootloader constraints. He holds a Master’s in Embedded Systems from AGH University and brings both leadership experience and low-level troubleshooting chops that often reveal edge-case failures before they reach customers.
