Look inside

Boutique FinTech company better-banking.io has a bold new idea. It wants to build an app that will give personal financial customers a better idea of how they’re spending their money, with an in-depth summary of every transaction. The company has hired you to build it for them.

You’ve decided to use Spring Boot and OpenAPI to build this banking app. Your challenges in this liveProject will include integrating with an external service, matching transactions to better-banking.io’s special database of merchant codes, and building an attractive UI that enhances bland financial readouts with company names and logos.

Once you’ve built the bones of your app, you’ll use Open API to integrate with an Open Banking Standard-compliant REST-based API. You’ll secure your new API with Spring Security, containerize it with Docker, and present your new app to your boss ready for your clients!

This project is designed for learning purposes and is not a complete, production-ready application or solution.
