Beschreibung

I am a Technical Lead and Senior Backend Engineer with a strong focus on building scalable systems and optimizing development and deployment processes.

I help companies improve system stability, accelerate delivery, and bring structure into complex architectures.

In my recent work, I reduced deployment times by ~90% by designing and implementing CI/CD pipelines and daemonless container build processes (Jib, Kaniko).

I combine hands-on development with architectural thinking and enjoy working at the intersection of backend, DevOps, and system design.
