Rockstar🎓
Top SchoolHayato Ohhashi is a Senior Embedded Software Engineer with a decade of experience building low-level systems, currently working on Linux kernel, hypervisor, and driver development at Qualcomm. He has a strong open-source pedigree: authoring Rust projects like KRaBs (the world’s first Linux-compatible Rust bootloader) and octox (a complete Unix-like OS) that reached Hacker News Top10, and contributing a performance patch to the Linux mainline for Xen timekeeping. Previously at AWS and as a university lecturer, he blends production-scale cloud support experience with academic teaching and research skills. Skilled in Rust and systems programming, he also implemented safe-data-structure libraries and even a Rust DOS executable, demonstrating both practical engineering and curiosity-driven experimentation. Based in Chiyoda, Japan, Hayato pairs rigorous low-level craftsmanship with a track record of influential open-source work that bridges research and real-world kernel/boot tooling.
