About me

By Christian Bargmann | | 4 minutes

I’m Chris Bargmann, a software engineer from Hamburg, Germany. 👋

I really enjoy learning (by building) about Distributed Systems and Developer Productivity Tools that focus on Observability, Reliability, Maintainability and Performance. I also enjoy working on Open Source Projects, most of my personal ones are available on my GitHub profile.

Today I am a longtime Gopher learning a little from the Rustaceans. In the past I worked on projects written in Java, Python, JavaScript, Lua and others. Still, I live in the clouds ever since and have sailed rough seas with Kubernetes and other cloud providers. Sometimes I blog and do talks. Happy to meet you someday.
