Hi!
I’m Dennis, a Site Reliability Engineering Tech Lead based in Stuttgart, Germany. I’m driven by a passion for observability (especially the Prometheus/LGTM ecosystem), building scalable cloud infrastructure, and writing code in Go and Python. With my Master of Science in Computer Science specializing in Cyber Security, I bring a well-rounded, security-conscious approach to my work at Flip App, a startup empowering employees.
Beyond Work
When I’m not ensuring systems run smoothly, you’ll find me serving my community as a volunteer firefighter or channeling my inner barista. I’m obsessed with the art and science of crafting the perfect espresso – constantly experimenting with beans, roasts, and brewing methods. Coffee is about the ritual, the pursuit of flavor, and the joy of each well-made cup.
