Overview
CityScout is a native iOS travel app built around a simple idea: travel feels better when the product understands the city, not just the booking. The iOS app keeps trip state close to the device, while a FastAPI backend handles itinerary generation, guide chat, and structured AI outputs behind a shared-secret auth boundary. A future web layer will support planning and sharing.
Why it exists
Travel planning usually ends up scattered across maps, bookings, reviews, notes, and too many open tabs. Most tools are good at booking things, not at helping someone actually feel oriented.
How it works
CityScout brings discovery, planning, and trip-time reference into one product. The iOS app stays close to the device, while the backend keeps AI calls server-side and the product contract easier to secure and evolve.
Built with
SwiftUI / SwiftData / FastAPI / OpenAI / Next.js
What I focused on
- Built a native iOS app with SwiftUI and SwiftData for local-first trip state.
- Designed a FastAPI backend with dedicated itinerary generation and guide chat endpoints.
- Kept OpenAI calls server-side behind shared-secret auth to avoid client credential exposure.
- Planned a Next.js web layer that reuses the same API contract for planning and sharing.
