Infrastructure and Platform Engineer who troubleshoots production systems.

Nearly six years in enterprise application operations, backed by hands-on Linux, Kubernetes, cloud infrastructure, automation, and recovery engineering.

I trace failures across application code, middleware, operating systems, networking, and dependencies—then turn the result into a safer operational decision or repeatable tool.

Based in Wroclaw, Poland. Focused on infrastructure, platform, cloud, systems, and production engineering roles.
