About Me

karaktaka avatar

I'm a passionate Lead AI Platform Engineer based in Hamburg, Germany. Fully specialized in cloud-first infrastructure.

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

Currently diving deep into AI-driven automation, I explore how large language models and agentic workflows can enhance developer productivity and streamline operations. Driving the Models to their limits and always try to enhance the setup by making it more efficient, intelligent and cost-effective.

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.
