Banking Sandbox API
Postgres schemas modelling accounts, transactions, and KYC.
A practice project modelling the moving parts of a small bank: accounts, ledgers, transactions, KYC state machines and audit trails — built on Supabase + PostgreSQL with row-level security enforced at the database.
Includes seedable test data, migration scripts, and a thin NestJS layer that exposes typed APIs to a React admin client. The whole stack runs locally with one command.
