About Me

I'm a product-minded technologist with a focus on infrastructure automation, containerization, and cybersecurity. Based in Berlin, I run a self-hosted homelab powered by Podman on Red Hat Linux, automate workflows, and explore AI-driven tooling.

Currently studying Business Administration at HWR Berlin, I bring a unique perspective that bridges technical systems with business strategy. I believe the best infrastructure serves people – not the other way around.

I'm looking for a junior role where I can grow as a DevOps engineer while contributing real value from day one.
