Herman Berget focused on stability improvements for the nrfconnect/sdk-nrfxlib repository, addressing two critical bugs in embedded Bluetooth Low Energy firmware. He resolved a GRTC interrupt issue in the Multi-Protocol Service Layer, preventing stack corruption during Zephyr initialization after soft resets. In parallel, he enhanced the SoftDevice Controller by fixing disconnections in multi-link encrypted scenarios, refining memory calculation macros and synchronizing versioning across build configurations. Working primarily in C and RST, Herman demonstrated strong debugging and RTOS skills, delivering maintainable updates that improved reliability and traceability in complex embedded systems without introducing new features during this focused engineering period.
