Jackpot GPS

Backend for a lottery-retailer discovery app. I built the REST API behind the Flutter client: nearby-store and heatmap endpoints, winner history, a scratch-off games catalogue, and subscription state gating premium data.

How it works

  • REST endpoints powering nearby-store discovery and the map heatmap regions.
  • Store winner history - prize amount, game and claim date - served per retailer.
  • A scratch-off games catalogue with search, price and status filtering.
  • Prize-breakdown data with premium gating, so full detail is served only to subscribers.
  • Supabase-backed auth flows including email verification and password recovery.
  • Subscription state and cancellation handling behind the checkout flow.
