TL;DR: Over the past year, I published Docker and Kubernetes Security, evolved the Docker Black Forest meetup into a CNCF chapter, delivered 15 global engagements across 6 countries, and joined LFX and GSoC as mentor. This post reflects on my journey from Docker Captain to CNCF Ambassador applicant, focused on education through storytelling and building secure supply chains.
In early 2024, I wrote an article titled How to Become a Docker Captain, chronicling my journey from a casual Docker user in 2015 to an official community leader. Today, as a Senior Backend Engineer at JobRad GmbH, a Docker Captain, and a Snyk Ambassador, my perspective on infrastructure has grown. Containers don't live in a vacuum—they are part of a massive, interconnected cloud-native ecosystem.
As I submit my application for the CNCF Ambassador program, I wanted to take a moment for a mid-year check-in to reflect on the community work, authorship, and open-source contributions I've been focused on between May 2025 and May 2026.
