Hi, I'm Paul.
I've been building software for nearly two decades. These days I build and run my own products, most notably 
Bullion API, 
PostConductor and Satzo. I write up the decisions behind each one as I go.
Based in the United Kingdom. Available for selected remote product engineering contracts.
