My name is Dennis and I am a 27-year-old Staff Reliability Engineer based in Aalen, Germany. I work at Flip App, a startup in Stuttgart that strives to empower every employee.

I’m passionate about Observability, particularly within the Prometheus/LGTM Ecosystem, and enjoy creating scalable and high-performance cloud infrastructure and applications. I am also deeply interested in software engineering and primarily write code in GoLang and Python. My Master of Science in Computer Science, with a specialization in Cyber Security, has equipped me with a comprehensive understanding of computing and security, which I apply in my daily work."

When I’m not working, I volunteer as a firefighter and serve as the assistant chief of a fire department. I’m proud of my dedication to serving my community and keeping people safe. I also have another passion that I devote a lot of time and energy to - being a home barista. I’m deeply in love with the art and science of crafting the perfect cup of espresso.
I have been refining my barista skills for years, constantly experimenting with different brewing methods, beans, and roast profiles. From pour over to espresso, I’m always looking for new ways to bring out the best flavors in each bean.
For me, making coffee is not just about the caffeine boost, it’s about the ritual, the attention to detail, and the experience of savoring every sip.
