Open to full-time roles · United States · Global Remote
4+ years building production e-commerce systems for a wholesale distributor: warehouse routing, order pipelines, search, and the APIs behind them. Right now I lead a legacy-to-modern storefront migration: an AI-agent pipeline I designed extracted 108 legacy features and shipped 41 rebuilt features, verified, in 18 days, with 497 tests passing on the new order and search layers.
Core technologies I work with
AI agents do the reading and the first drafts. I design the pipeline, review every claim, and own what ships.
Proof
A six-phase agent pipeline I run extracted 108 legacy features and shipped 41 rebuilt features, verified, in 18 days. This site's assistant runs on Cloudflare Workers AI with rate limiting and an offline fallback.
