Summary
🤩
Rockstar🎓
Top SchoolSigvart Hovland is a Software Engineer II based in Trondheim with 12 years of embedded systems experience building secure, low-power IoT firmware and tooling. He has shipped production bootloader and DFU improvements at Nordic Semiconductor and now contributes to secure IoT stacks at Silicon Labs, with hands-on expertise in embedded C++, Python automation, Zephyr, and nRF platforms. An active open-source contributor, Sigvart has added cryptographic backend support and CC310 integration to mcuboot and refined image validation in the nRF Connect SDK, underscoring his focus on secure firmware update paths. He pairs deep firmware design skills with practical tooling and CI work, improving developer experience and system reliability. Known for a pragmatic, problem-first approach—humorously summarized on GitHub as “Fixing problems by creating bugs”—he often surfaces subtle cross-layer issues between bootloaders, crypto hardware, and modem firmware.

Secure boot for 32-bit Microcontrollers!
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:12 reviews, 12 commits, 16 PRs in 4 years
Contributions summary:Sigvart primarily contributed to the secure boot process for 32-bit microcontrollers, focusing on integration with the nRF CC310 cryptographic co-processor. Their work included adding a glue layer for the CC310, integrating it with existing bootloader interfaces, and addressing bugs related to CC310 usage. Furthermore, they refined existing functionality by adding features for multiple crypto backend support and fixing an error with a core disable function.
