About Me

Hi, my name’s Matthias. Over the past 20 years, I have been developer, architect, release engineer, scrum master, project lead, tech lead and director.

No matter the role, I love software engineering, smiling customers and winning as a team.

My values are Openness, Knowledge Sharing, Teamwork and Sustainability.

I also value source code over slides. I like to release early and often.

I am fluent in German, English and French.

My current centre of interest is machine learning.
