Portrait of Roman Mednitzer

Roman Mednitzer

Vienna, AT · Senior Platform & Infrastructure Engineer · Linux · Kubernetes · GitOps

Production Linux, Kubernetes, and GitOps in regulated environments. Audit-defensible operations under ISO 27001 and NIS2.

About

Ten-plus years operating production infrastructure in regulated and business-critical environments, including medical-device manufacturing. Day-to-day: Linux, virtualisation, Kubernetes, monitoring, and backup/DR with verified restore. Work that has to hold up under change management and audit.

Focus: the seam between platform operations and systems assurance. Policy-enforced delivery, runtime control points, and evidence chains mapped to ISO 27001 and NIS2, with EU AI Act and CRA obligations approaching.
