## Overview

This repository is a set of JEE/Spring and Angular practice applications, culminating in a bank-management application. Its user-facing workflows range from product CRUD (REST or web pages) to banking: users authenticate, browse customers and accounts, and view or perform account operations. The bank backend separates REST endpoints, service logic, DTO mapping, and persistence; its Angular frontend provides routed screens and authentication. Evidence is uneven: sampled code establishes key bank and product-backend calls, while several documented or tree-visible subsystems are represented without speculative internal links.
