About Me

karaktaka avatar

I'm a passionate Lead DevOps System Engineer based in NRW, Germany. Fully specialized in cloud-first infrastructure, I live and breathe Kubernetes, EKS, and increasingly AI-driven automation.

My journey started as a systems apprentice in 2010 and evolved through sysadmin roles into the DevOps world — where I found my sweet spot: multi-cloud engineering, GitOps, and making large-scale distributed systems run reliably.

When I'm not shipping infrastructure code, I'm gaming, running the NerdyCraft community, or building something with AI that probably could've been a shell script.
