Rockstar🎓
Top SchoolFrederic Cambus is a system and network engineer with 14+ years building portable, maintainable, and secure C-based services and high-availability infrastructure across Linux and *BSD. He develops performance-oriented APIs (notably an IP Geolocation service built on the Kore framework) and audits toolchains and compiler security features using GCC and LLVM on diverse architectures. An active contributor to NetBSD and OpenBSD, he maintains ports, backports security fixes, and has worked on kernel console subsystems and source-based code coverage for LLVM. Comfortable across back-end development, DevOps and DNS administration, he also automates deployments and refines build systems (pkgsrc, Rust tooling, ELF utilities). Outside typical sysadmin work he pursues niche interests—ANSI art and text-mode tooling—reflecting a long-standing affinity for low-level systems and tooling ergonomics.
