PROFILE

Henrik Lander

Henrik Lander developed and optimized Bluetooth provisioning workflows in the nrfconnect/sdk-nrf and nrfconnect/sdk-nrfxlib repositories, focusing on multi-device connection strategies and radio stack reliability. He engineered reusable sample applications in C and CMake that demonstrated concurrent scanning and connection modes, accelerating device onboarding and internal validation. Henrik addressed race conditions and improved configuration consistency, enhancing stability for Bluetooth Low Energy peripherals. He also fixed critical bugs in the radio event recovery logic and implemented boundary checks to prevent out-of-bounds access, increasing safety and maintainability. His work reflected a deep understanding of embedded systems, firmware development, and version control practices.
