Summary
👤
Senior🎓
Top SchoolSlawomir Wojtczak is a seasoned infrastructure architect and entrepreneur with 14 years of hands-on experience designing and operating UNIX-based systems, storage, backups, clusters, and virtualization across FreeBSD, Linux, AIX, Solaris and HP-UX. As founder and CEO/CTO of Vermaden Enterprise and a long-time consultant, he blends deep technical craftsmanship—ZFS, FreeBSD jails, rsync/automation, IBM Spectrum Protect/Bareos—with strategic architecture work for enterprise clusters and storage arrays. He has driven R&D and production deployments at organizations like PGE, IBM and Kyndryl, building resilient, highly-available systems and bridging open-source solutions with enterprise products. Notable practical strengths include FreeBSD package infrastructure (poudriere/pkgbase), secure NFSv4 in VNET jails, and inventive use of efibootmgr for ZFS boot mirrors. Based in Łódź, Poland, he favors pragmatic, open standards-first approaches but chooses paid enterprise tools when they deliver measurable operational value. His profile combines founder-level leadership with deep low-level systems expertise, making him a go-to architect for complex storage and virtualization challenges.
