intro

Kevin Murphy, in one page.

Senior full-stack software engineerDeloitte since 2021Tempe, AZ

I ship production software end to end: React and TypeScript on the front, Node.js and NestJS on AWS behind it, and the data model in between. Eleven years in, five of them on federal-scale systems (FedNow, IRS.gov, Michigan unemployment insurance) and three on the ASU Mobile App.

In 2026 I have been shipping applied AI features in the open: retrieval, agent loops, tool design, and the evals that keep them honest. Twelve open-source projects, ten with live demos.

Open to conversations about senior and mid-level full-stack and product engineering roles. Remote from Tempe, hybrid in the Phoenix area, or relocation for the right team.
