Professional Summary
Backend-focused full-stack developer with 10+ years building and maintaining high-availability web applications and APIs. I've led technical initiatives, modernized legacy codebases, and mentored other engineers along the way, and I still care most about clean architecture and cutting the manual work that doesn't need a human doing it.
