GO BANK

A simple banking application back-end built with Golang and PostgreSQL.

Learning about how to design, develop, and deploy a complete backend system from scratch using Golang, PostgreSQL, and Docker.

Built with Test-Driven Development (TDD).

Project is currently put on hold.

Go bank service

This service is for a simple banking app. It will provide APIs for the frontend to do following things:

1. Create and manage bank accounts, which are composed of owner’s name, balance, and currency.
2. Record all balance changes to each of the account. So every time some money is added to or subtracted from the account, an account entry record will be created.
3. Perform a money transfer between 2 accounts. This should happen within a transaction, so that either both accounts’ balance are updated successfully or none of them are.
