## Overview

FinGenie is a banking and personal-finance application with web flows for authentication, account transactions, investments, loans, and administration. The principal user workflow is to register or log in, verify an OTP, then use authorized banking or wealth features; administrators also manage users and monitor operations. The graph preserves those product areas while limiting backend call edges to relationships visible in sampled source. Other service wiring and frontend API usage are not established by the available excerpts.

Main entry points: [`Frontend/src/App.js`](https://github.com/abhinay6677/fingenie_capstone_project/blob/main/Frontend/src/App.js) (Route application), [`Backend/auth-service/src/main/java/com/wipro/auth_service/controller/AuthController.java`](https://github.com/abhinay6677/fingenie_capstone_project/blob/main/Backend/auth-service/src/main/java/com/wipro/auth_service/controller/AuthController.java) (Auth endpoints), [`Backend/auth-service/src/main/java/com/wipro/auth_service/service/AuthService.java`](https://github.com/abhinay6677/fingenie_capstone_project/blob/main/Backend/auth-service/src/main/java/com/wipro/auth_service/service/AuthService.java) (Registration service), [`Backend/auth-service/src/main/java/com/wipro/auth_service/repository/UserRepo.java`](https://github.com/abhinay6677/fingenie_capstone_project/blob/main/Backend/auth-service/src/main/java/com/wipro/auth_service/repository/UserRepo.java) (Auth user store)
