Diego Balaguer
Didac Balaguer contributed to the IT-Academy-BCN/ita-challenges-backend repository, focusing on backend feature delivery, domain refactoring, and API reliability over three months. He restructured core submission and favorite modules for clearer domain models, aligning endpoints and improving maintainability. Using Java, Spring Boot, and MongoDB, Didac implemented rigorous test-driven development, expanded test coverage, and standardized error handling with centralized DTOs and enums. His work included Gradle build optimizations, documentation updates, and release management, reducing technical debt and onboarding friction. These efforts stabilized API behavior, improved error reporting, and established a robust foundation for future feature expansion and client integration.
