Tip: show the Validation Errors screenshot during interviews to highlight `@Valid` and centralized `@ControllerAdvice`.

Designed and implemented a hybrid backend that exposes the same To-Do domain through both a JSP-based MVC UI and a JSON REST API, demonstrating separation of concerns and reusability of business logic.

Scope: 15+ REST endpoints · Centralized validation & error handling · Dual DB profiles (H2 / MySQL)

  • REST API: Full CRUD with correct HTTP verbs and `ResponseEntity` wrappers.
  • Validation & Errors: `@Valid` DTOs, centralized `@ControllerAdvice` returning structured JSON `errorDetails` payloads.
  • Persistence: Spring Data JPA + Hibernate; H2 for local dev, MySQL config (Docker-ready) for production.
  • Security: Spring Security with BCrypt, in-memory demo users and role-based access control.
  • Dev Experience: `data.sql` for bootstrapped demo data; profiles for quick dev ↔ prod switch.
  • API Docs & Observability: Integrated `springdoc-openapi` (Swagger UI) and Spring Boot Actuator for metrics & health endpoints.
