Create a new Backend for Frontend and Frontend POC for Apache Fineract

My name is Edward. I'm a Master’s student at the University of Colorado Boulder in the US and I am passionate about Apache Fineract’s mission to improve the availability of financial services to people all over the world. Apache Fineract provides core banking APIs, but lacks a community-maintained layer for end-users. The former Self-Service API was removed, leaving vendors to build their own frontend from scratch. To support this new frontend, I am proposing a new Backend for Frontend (BFF) and associated frontend that enables improvements to end-user security, reliability, performance, and auditing. The focus of this project is to build a POC that is well-tested and documented so we can build a "release-ready" solution in the future. Deliverables include: 1) Standalone Spring Boot BFF application with its own user model and JWT-based authentication 2) Feign client integration with Fineract's core API via a dedicated service account 3) API Aggregations for User data summaries, account information, loan and savings views, and transaction capabilities 4) User registration flow with OTP and Identity Verification 5) User login flow with 2FA 6) Auditing for Basic Frontend Concerns 7) Open Banking Authentication Flow 8) A working frontend to demo these features Some stretch goals include but are not limited to: 1) MPIN for transaction authorization 2) Rate Limiting 3) HSM key storage
