The constraint
Clients need to find nearby professionals and book available appointments. The API also needs to support payments, product orders, and separate permissions for clients, professionals, and administrators.
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.
