Senior🎓
Top SchoolApollon Oikonomopoulos is a seasoned technology leader and Chief Information Officer with 16 years of hands-on experience designing, building, and operating resilient infrastructure for high-traffic services. Trained as a mechanical engineer, he transitioned into systems administration and platform leadership, progressing from sysadmin roles to head of infrastructure and director of engineering before becoming CIO at Skroutz. He is an active Debian Developer and prolific open-source contributor with reliability-focused patches to projects like the H2O web server, Ganeti VM cluster manager, and the tgt iSCSI target—work that improved stability, compatibility with modern compilers, and cross-platform operability. Known for blending deep operational knowledge with software craftsmanship, he drives both DevOps automation and low-level correctness (e.g., fixing race conditions and pointer/overflow bugs). Based in Athens, he pairs enterprise leadership with community-minded contributions to foundational tooling many production systems depend on. An understated strength is his ability to translate infrastructure-level fixes into measurable production improvements, from boot-time service notifications to safer SSL and I/O handling.
