About Me

Hi, I’m Chris, and I’m a Software Engineer from Munich, Germany. I focus on Back-End Web Development and CI/CD to bring reliable products to users. I’m currently studying Business Information Systems (M.Sc.) at the Technical University of Munich (TUM), but I’ve learned most of the interesting stuff through my own projects and my desire for new experience. Programming as a craftsmanship is my main hobby, learning something new keeps me motivated. Lately Golang got my attention, Blockchain technologies are also on my radar. On the web you’ll find me as @arubacao.
