Technology stack: Java, Spring, Hibernate, Thymeleaf
Assumption: Since one user only has one wallet, for the sake of this tech challenge, User modal is directly linked with transaction account, thus not providing endpoint to create a new wallet for user. Endpoint is provided for create a new user. Since Hibernate(in-store memory store) doesn't support dynamically generate table feature, this demo is only demonstrating two transaction accounts(primary and savings). Multiple transaction account feature (including create new trasanction account) should be able to be extended in the future. Testing for concurrent is not implemented as testing with multithread(e.g.testng) doesn't seem like supported by Spring.
