Wrocław, Poland · Remote friendly
About — readme.txt
Self-taught, into computers since I can remember. I work across the dev/ops boundary — writing the infrastructure code one day, debugging what broke in production the next. Hands-on experience spans cloud infrastructure, container orchestration, CI/CD pipelines, and system administration, from bare metal to multi-cloud.
