Isaac Diez
Contributed to the IT-Academy-BCN/ita-challenges-backend repository by designing and implementing modular backend features focused on secure API development, authentication, and GitHub integration. Delivered reusable JWT and GitHub core modules, centralizing token and user validation logic to improve maintainability and scalability. Applied Java, Spring Boot, and Gradle to refactor authentication flows, enhance test coverage with JUnit and Mockito, and enforce robust error handling. Strengthened CI readiness through changelog management, documentation updates, and configuration improvements. The work reduced invalid user data risk, clarified API boundaries, and enabled more reliable, testable microservices, supporting both business value and developer productivity across the project.

Sep 1, 2025September 2025 performance highlights for the IT-Academy BCN backend (ita-challenges-backend). Focus was on strengthening GitHub integration, enforcing GitHub-based user validation, and improving code quality and test coverage. Delivered a decoupled Github Core module with GithubApiService and GithubConfig (including application.yml wiring) and integrated core config across services. Implemented GitHub username validation in the user microservice with dedicated GithubUserNotFoundException and expanded tests, and applied GitHub username verification across the user flow. Expanded test coverage (including ExternalGithubServiceImpl tests) and performed PR-driven refactors to align with branch 649 changes, peer review feedback, and standardize code (Lombok refactor, @Service annotation). Documentation improvements include a Github Core README. These efforts collectively reduce invalid user data risk, improve reliability and maintainability, and strengthen CI readiness and business value.
