About Mike

I’m an independent open source software developer based in Portland, OR. I’ve been writing software since 1993 and open source since 1995.

Today I’m the founder and CEO of Contributed Systems, my own company dedicated to building and supporting open-source-based application infrastructure.

When you email Contributed Systems, you get me. There are no layers of bureaucracy or support to navigate.
