Overview

Built for a repeat client who needed a polished AI travel assistant. The app takes user preferences — destination, budget, hotel type, interests, meal preferences — and generates a fully detailed day-by-day itinerary using the Claude API with up to 16,000 output tokens.

The project went from spec to live deployment on a DigitalOcean VPS with SSL, Nginx reverse proxy, and systemd service management.
