I like to build simple, secure and resilient information systems to empower and connect people. I believe that this is best done with Free Software, open data standards, open protocols, and restrained craftsmanship.

I am happiest when I get to do this work with those fighting fascism, ethnic-cleaning, genocide and protecting our environment.

To make a living, I provide consulting and coaching services for software, data, and security engineering.
