Hiya!
I'm Andrew. A father, husband and software engineer living in Scotland.
I've been building software since Turbo Pascal on an Amstrad - an old language no one remembers on an old computer no one used.
During the day, I work at TransferGo as a Staff Engineer. I've built Compliance, Risk and Anti-money Laundering things, then rebuilt the Profiles domain. Now I've joined the Developer Experience team, helping engineers get better at working with AI.
I'm teaching software development concepts using metaphors on YouTube and writing interactive and animated articles.
My spare time is spent with family, kayaking, 3D printing, and coaching youth football.
