PopSpot.
Cross-platform mobile app connecting pop-up vendors with nearby customers. Dual-role experience: vendor event management with live status/inventory; customer discovery via interactive map and feed.
PopSpot is a cross-platform mobile app (iOS + Android) built with React Native and Expo that connects local pop-up businesses with nearby customers. Vendors post temporary events — food trucks, craft fairs, pop-up cafés, markets — and customers discover them via an interactive map or scrollable feed. The vendor side supports a full event lifecycle (upcoming → open → closing_soon → sold_out → closed), per-product inventory updates, and a business dashboard with follower stats and review aggregates. The customer side provides a filterable explore feed, a full-screen React Native Maps view with status-coded markers, event bookmarking, business following, and a 1–5 star review system. The database is 11 tables on Supabase PostgreSQL with RLS policies enforced at the DB layer. Two database triggers maintain denormalized follower_count and avg_rating fields so business card renders never require expensive aggregate joins. The app runs React 19 Compiler (automatic memoization) and New Architecture (Fabric + TurboModules) for improved scroll and animation performance.
Problem
Pop-up businesses suffer from a discovery gap — no permanent storefront, no reliable foot traffic, no unified marketing channel. Customers who want to support local vendors simply don't know where or when to find them.
Solution
Dual-role mobile app: vendors control their live status and inventory in real time; customers discover nearby events via map markers color-coded by status. DB-level triggers maintain aggregate fields for fast reads at scale.
