I build the thing and make sure it sticks.

Josh Rainboldt

Twelve years shipping software and keeping it running inside real businesses.

I build software end to end: backend systems, frontends, infrastructure, and the glue in between. When I'm not shipping code I'm chasing creative hobbies that keep the engineering brain honest. This is where I keep my projects, writing, and the occasional experiment.

A full-stack web app that replaced manual vlookup-based data imports into Salesforce — OAuth for access control, matching algorithms to resolve emails to ContactIDs and websites to AccountIDs, a user review step before commit, and BigQuery for persistent audit logging.
