Latest project
Casa AI Agent
AI voice reservation PoC
AI-powered voice reservation system built as an end-to-end production PoC. A Vapi voice agent takes phone reservations through n8n and FastAPI, applying business rules for party size and daily capacity before persisting to PostgreSQL. A Next.js admin dashboard lets staff review, confirm and manually create reservations against the same FastAPI backend.

Visit project Web Relaunch
Old site? Time for a fresh menu.
New website — or a tasty redesign of the old one.
If your site loads slow, looks dated, or just doesn't represent you anymore, I'll rebuild it from scratch: fast, modern, mobile-first, and easy to keep fresh long after launch.
First relaunch projects are currently cooking — case studies coming soon.
