I build tech products to solve hard problems
I'm Spencer, Senior Ruby + Python Developer with over 11 years of experience working across public, private and non-profit sectors.
You can find my work in UK Government Digital Services and powering global conservation efforts.
I write about the art and architecture of building good software products. I'm currently building things to do with trade tariffs at HMRC.
