I'm Daniel (he/him). I am an experienced leader in the Ops/Platform/DevOps/SRE space with a passion for people AND technology.
My professional journey started in a classical IT operations role in 2000, managing systems for an online Bank. I've traversed through big corporates and small startups, and I'm currently working for Gini, a German FinTech, and I'm in charge of the platform and IT. My responsibility is to enable cross-functional product teams with a platform based on Kubernetes for fast and reliable delivery. Millions of people use the platform in Europe each month.

- Python: Mostly for more straightforward tasks and one-offs
- Bash: You can get pretty far with it
