Summary
🤩
Rockstar🎓
Top SchoolDaniel Schäfer is a system software engineer with 11 years of experience building and upstreaming low-level firmware and platform software, currently driving system software at Framework in Taiwan. He has a strong track record in UEFI, OpenSBI/RISC‑V bring‑up, EC and keyboard firmware, and cross‑OS kernel drivers (Linux, Windows, FreeBSD), frequently contributing to prominent open-source projects like EDK2 and OpenSBI. At HPE he owned UEFI for ProLiant platforms, improved CI/build tooling, and shipped firmware management and virtualization-adjacent features, showing an ability to take ownership from prototype to production. Comfortable across firmware, kernel, and userland stacks, he pairs hardware-focused engineering with practical tooling and release discipline. A multilingual engineer with a background in applied computer science and hands-on projects from PCIe auth prototypes to web platforms, he blends systems expertise with a habit of open-sourcing significant portions of his work.
