Top SchoolRoeland Jansen is an experienced Linux/Unix infrastructure engineer and technical specialist with over 11 years in enterprise environments and a background in avionics dating back to a two-decade career at KLM. He has led and delivered complex infrastructure projects across finance, telecom, utilities and engineering firms—working with RHEL/SLES, ESXi, SAN, networking (Cisco/Juniper) and virtualization for large fleets and mission-critical services.

He tests hardware and navigation software for well-known vendors and has a history of low-level C tooling (PC-MOS/386), showing a mix of kernel-adjacent curiosity and practical operations skill. Certified in electronics/telecom and as a ham radio operator, he brings uncommon cross-domain discipline from avionics and radio to modern datacenter practices. Based in 's-Hertogenbosch, he balances technical depth with people-focused delivery and a penchant for electronic music and hamradio culture.
