Spontai
An AI travel planning app that turns a destination and a date range into a personalised itinerary. Built solo as founding engineer, now live on the App Store in the UK and US.
Planning a trip means a dozen open tabs, a group chat nobody reads back, and a spreadsheet that goes stale the moment plans change.
Co-founder & CTO. I own the product, the AI pipeline, and the infrastructure — from the first prototype to what ships in production today.
Live on the App Store in the UK and US, with fortnightly releases shaped directly by 50+ TestFlight feedback items per cycle.

Product & Founding
Defined the roadmap and shipped fortnightly, prioritising against 50+ pieces of TestFlight feedback per cycle rather than internal opinion.
RAG Pipeline
Built the retrieval-augmented itinerary engine — routing between Claude and OpenAI, grounding generations in pgvector embeddings of real travel data.
Data & Infrastructure
Owns Supabase end to end: 60+ migrations and 20 edge functions covering auth, itinerary state, and background jobs.
Ops & Monitoring
Wired up Sentry for crash reporting and per-provider LLM cost tracking, so a spike in spend or errors surfaces before users notice it.
