I have worked in developer teams, an operations team, and been a generalist shipping software for JUST EAT since 2010 (with a few years doing that elsewhere first). I've lived through cultural and technological change and played a role in effecting it. I had a pivotal role in migrating our platform from a datacentre to the AWS cloud - consequently, we now do tens of deployments a week compared to a tens a year. I've automated systems, tests, servers, and in some cases myself. I've touched many parts of the platform and delude myself that I do an OK job at that.
