Summary
🤩
Rockstar🎓
Top SchoolSebastian Głąb is a software test engineer with four years of professional experience in embedded systems and IoT, currently at Nordic Semiconductor in Krakow. He brings deep hands-on expertise in hardware-software integration—adding device tree/board support, low-power modes, and stress tests for SPI/I2C peripherals—to widely used projects like nRF Connect SDK and the Zephyr RTOS. His background spans automotive systems testing at Aptiv, FPGA/ASIC and ARM Cortex-M firmware development from research at AGH, and experimental detector work with CERN’s LHCb, giving him uncommon fluency across test design, hardware bring-up, and system-level validation. Known for improving driver robustness and test coverage, he combines rigorous test automation with field-oriented stability testing in climate chambers and power-constrained environments.
