Look inside
BestInsurance has a rapidly growing customer base and happy front-office employees, thanks to a newly built API that lets customers subscribe to policies and lets front-office employees narrow their searches with custom filters. But the back-office staff is unhappy with the high latency of the user interface. As a backend developer, you’ll solve this problem by adding pagination with Spring Data JPA, preventing the page from loading all the customer data at once. You’ll use JPQL to add aggregate functions that return information the back office needs, such as revenue and customer count by state. You’ll implement a REST service for uploading policy subscription data provided in CSV format and importing it into your database. You’ll also leverage domain events for sending messages when subscriptions are saved, updated, or deleted. When you’re done, you’ll know how to add REST API services, and the back-office employees will thank you for making their jobs easier!
This project is designed for learning purposes and is not a complete, production-ready application or solution.
