Tester · Developer · Runner

I've been testing software since 2009 and writing code for over ten years. At Simply Business I coach my squad on quality and maintain the test tooling around 90 engineers use every day. I build websites for small businesses as Little Oceans, and at weekends I run ultra-marathons, ideally over mountains. Family man first. I notice details, and I believe in Oxford commas.
