Who am I?

DevOps Engineer passionate about automating everything and making systems bulletproof.

I've spent the last 2 years building and maintaining critical infrastructure — from Kubernetes clusters serving 10,000+ daily users to CI/CD pipelines that actually work. Started as a system administrator, evolved into someone who thinks in Infrastructure as Code.

What I do best: Kubernetes/OpenShift orchestration, Jenkins automation, monitoring with Prometheus/Grafana, PostgreSQL optimization, and writing Python/Bash scripts that save hours of manual work.

What I'm exploring: AWS cloud architectures, preparing for CKA certification, diving deeper into GitOps workflows.

When I'm not in the terminal, I'm probably troubleshooting something that "should work but doesn't" — and finding creative solutions outside the official docs.
