Peter Day / Senior Full-Stack Engineer/ Gloucester, UK
Senior full-stack engineer with 15+ years building high-availability platforms. Ex-CTO of Quuu, now building AML screening at Experian.
I've spent fifteen years building platforms people depend on every day. Seven of them as CTO of Quuu, rebuilding it end to end without a single customer-facing outage. Today I help organisations catch financial crime at Experian. I like calm systems, honest code, and interfaces with a little colour in them.
