What I'm looking for

I'm looking to partner with business leaders on complex, high-impact products where I can use AI-enabled full-stack development to rescue stalled initiatives, modernize legacy systems, or build revenue-driving products from zero to one.

At Savantly, I partner with enterprise clients to rescue stalled initiatives and ship end-to-end full-stack features, including an AI-powered Rails and React website builder and a production RAG help assistant.

I've built products from zero to one across Sola Salon Studios, Motigo, and Engine: scaling a national franchise from 15 to 500+ locations, supporting 10,000+ concurrent users during a live audio event, and launching a booking engine that reached 50,000 monthly bookings within six months.

I combine Ruby on Rails, React, React Native, cloud architecture, and LLM workflows to modernize monoliths, build pragmatic APIs, and deliver software users love.
