I'm a professional and experienced software developer based in
Cambridge, UK. By day I work as a Ruby engineer at the accountancy
startup FreeAgent, helping to grow software with lots of happy
customers. By night I curate the devops weekly email newsletter, hack
on various open source projects, organise local meetups in London and
write tutorials or articles about software development and web
operations.
