I makethings.

Software, systems, experiments, music, and whatever I happen to be obsessed with.

●  03 / The labExperiments & rabbit holes

Small experiments.
Big learning.

A collection of side projects, prototypes and ideas that probably didn't need to exist — but were fun anyway.

●  05 / AboutLong story, short

I've been building software since 2002.

I've worked on enterprise systems, fintech, cloud infrastructure, products, teams and all sorts of things with too many moving parts.

These days I'm more interested in making things than talking about making things.
