PROFILE
Håkon Edøy Hanssen
Contributed to the nrfconnect/sdk-nrf repository by delivering targeted improvements in embedded systems and firmware development. Enhanced modem initialization reliability for nRF91 development kits by adjusting timing parameters in C, reducing startup failures and improving device stability. Developed a feature to enable SSL session caching in the psa_tls sample, optimizing secure communications through reduced TLS handshake overhead and better runtime performance. Expanded platform support for NRF54H20DK in crypto samples, reorganizing YAML-based configurations and improving tagging for easier discoverability. Demonstrated a methodical approach to configuration management, cryptography, and network programming, focusing on maintainability, hardware coverage, and performance-oriented security enhancements across the codebase.
