Senior🎓
Top SchoolHeiko Stübner is a seasoned embedded Linux developer with 16 years of experience specializing in low-level kernel, bootloader and Trusted Execution Environment work for Rockchip SoCs. As long-time maintainer of Rockchip support in the Linux kernel and contributor to projects like OP-TEE, ARM Trusted Firmware and OpenSBI, he combines hardware-aware driver development with secure-boot and PMU expertise. Heiko builds and debugs plumbing-layer software (U-Boot, Yocto, device trees, clock and power domains) that enables mobile and IoT platforms to boot and run reliably. Currently at CHERRY Digital Health and active in the upstream Linux community, he has a track record of turning SoC-specific quirks into maintainable kernel subsystems. His background spans RISC-V platform work and OP-TEE adaptations, reflecting a rare mix of security, platform bring-up and performance-monitoring experience. Based in Dresden, he also brings Debian packaging and longstanding open-source stewardship to product-focused engineering.
