Hallo, Hi, Bonjour

I am Matthias, a software engineer and architect based in Montréal, originally from Germany. I currently work at Opal on the open-source Opal platform that helps patients access their medical data.

I like building maintainable software and turning real-world problems into reusable solutions.

My style is hands-on and systems-oriented. I have a strong bias for action, am comfortable wearing many hats, and stay product-focused from idea to delivery. I care a lot about automation, code quality, and long-term maintainability.

Open source is a big part of how I work. I regularly contribute upstream, share what I learn, and document solutions so others (and my future self) can reuse them.

On this site, you will find practical technical write-ups: setup guides, debugging notes, migration workflows, and lessons learned from real projects.

Outside of tech: table tennis, squash, and great coffee.
