About Me
Computer science is my passion
Hello, I'm a Full Stack Developer and DevOps Engineer. I have a degree in applied computer science, which I obtained at the cooperative state university in Karlsruhe back in 2016. Over the years I have acquired deep analytical skills. I have very good knowledge in the areas of J2EE, Angular, Kubernetes and SAP Commerce. In my free time I like to deal with the "new hot shit" and I'm generally always looking for new challenges. So far, everything from smart home to server hosting was included. This website also runs in my Kubernetes cluster on my server at home.
