Jay Hayes is a Senior Software Engineer with 14 years of experience delivering reliable, test-driven backend systems and leading engineering teams. Based in Florence, Alabama, he has moved from hands-on Rails development and teaching at Big Nerd Ranch to product leadership roles at Stitch Fix and currently Angel Studios, combining deep technical craft with mentorship. A committed advocate for testing and robustness, Jay has contributed to major open-source projects including Ruby on Rails and RSpec—fixing database task behaviors and hardening error handling in widely used libraries. He excels at improving legacy codebases and launching new products, notably helping Stitch Fix enter the kids market and rebuilding a congressional database earlier in his career. Colleagues know him for clean design, thorough test coverage, and an unusual habit: he treats rake tasks and formatter specs with as much care as user-facing features.
