PROFILE
Erik Bérceš
Contributed to the nrfconnect/sdk-nrf repository by developing and refining embedded networking features, focusing on Wi-Fi configuration modernization, MQTT reliability, and documentation clarity. Addressed stack overflows in MQTT samples for RAM-constrained devices using C and YAML, and improved onboarding by standardizing configuration references. Enhanced Zephyr Wi-Fi sample documentation to align with current hardware support, removing deprecated options and clarifying build instructions. Led targeted codebase cleanups, reducing repository bloat while retaining essential CoAP and MQTT-SN samples. Demonstrated disciplined configuration management, technical writing, and real-time systems expertise, ensuring maintainable code and reliable developer experience across Zephyr RTOS and nRF Connect SDK platforms.
