Senior🎓
Top SchoolRobert Nagy is a seasoned systems engineer and open-source contributor with 21 years of experience building and maintaining complex server farms across OpenBSD, FreeBSD, Linux, and Windows. He combines deep UNIX networking expertise with back-end development in Ruby, PHP, Perl, POSIX Shell, SQL, Lua, and C to deliver reliable, portable services and scalable infrastructure. An active OpenBSD maintainer since 2004, he has ported major software (LibreOffice/OpenOffice, Chrome, Mono), integrated upstream changes, and worked on BSD ports and package systems to ease long-term maintenance. In Mono, he implemented OpenBSD-specific garbage collection and runtime support, fixed build issues, and addressed data segment and dynamic library handling, demonstrating strong low-level OS and runtime knowledge. He has led system-design work in OpenBSD ports, including build configurations and unveil-based security hardening, and currently holds developer roles at FreeBSD, Mtier Ltd, and The Document Foundation. Based in Dunakeszi, Hungary, his career blends production-grade administration with hands-on development to drive portability, redundancy, and performance across heterogeneous environments.
