Principal engineer who still loves shipping — Rails, React, and AI that actually ships.
I work on hard problems in mature systems: Rails monoliths that need modernizing, AWS bills that need trimming, and the occasional RAG pipeline bolted onto a 10-year-old codebase because it solves a real problem, not because it's trendy. Augment, don't rip out. If you want someone who reads diffs and docs with equal enthusiasm, we'll get along.
