Kianzo worked on the ahumadamob/springboot-calificaciones repository, building foundational backend features to support teacher and course enrollment management. He implemented the Docente and Cursada entities with full CRUD operations, structuring the codebase using a clean controller-service-repository pattern. Leveraging Java, Spring Boot, and JPA, Kianzo established RESTful endpoints that enable scalable data operations for both teachers and enrollments. His work focused on maintainable architecture, laying the groundwork for future reporting and analytics. The codebase reflects clear entity modeling and readiness for further testing and enhancements, demonstrating depth in backend development and a methodical approach to system extensibility.
