## Summary

Senior Ruby on Rails engineer with 15+ years building high-traffic, backend-heavy SaaS products — including helping launch SurveyMonkey CX from zero. For the last few years I've focused on integrating AI and LLMs into Rails applications: calling models from app code, experimenting with retrieval (RAG) and agentic frameworks, and keeping that work isolated behind background jobs so the rest of the app stays fast. I care about the production details — timeouts, retries, failure handling — that decide whether an AI feature is a demo or a dependable part of the product.
