About us

We love solid design, stable code and having fun. Our personal projects include mobile, web and desktop apps, as well as small hardware based on RPi and Arduino.


For work, I manage large enterprisey systems. We also provide architecture consultation for everything from a single app to multi-system integrated solutions.

Our mission

At Coder.Haus we want to have fun and make cool things. If we also help people make a difference in society, all the better! We’ll never shy away from a challenge, and seek these opportunities to grow.

Our history

I started my love of technology back in the 1980s fixing VCRs and cassette decks. Along the way I learned how to code, and at some point figured out how to combine my love of hardware and software. I have helped build electronics manufacturing and repair companies, written mobile apps for the enterprise, and designed and implemented integration solutions that provide real time data to patients and clinical staff.


A few years ago my son joined me in my love for technology. From gaming to making, to 3d and print design, we have helped each other grow in depth and breadth.


We are industry experts with more than 15 years of experience.

I love solid, simple design. I am an AWS Certified solutions architect and have overseen the implementation of small systems used by dozens, to large enterprise systems, both on-prem and private/public cloud.

I also love the smell of solder (almost as much as the smell of tacos).


I run, I read, I code.

Art is my jam. Video games are my life.
