About

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.

Multi-cloud infrastructure (AWS, Azure, OpenStack)
Kubernetes & Docker orchestration
CI/CD & GitOps automation
