The constraint
Two-sided marketplace with real constraints: live availability, location-based discovery, payments that can't silently fail, and role-separated views for clients, pros, and admins, all on top of one consistent data model.
The approach
React Native on top of a Node + Postgres services layer, with the schema designed around booking and availability invariants, Paystack integration scoped carefully around failure modes, and a role-aware API surface shared by every client.
