Worked on the MarianoEPN/ProyectoDisenio repository to design and implement an initial accreditation database schema, focusing on structuring tables for careers, subjects, and learning outcomes while maintaining referential integrity. Used SQL to define relationships and ensure data consistency, and managed schema changes through a dedicated implementation script. Prioritized repository maintainability by removing obsolete scripts and documenting the deprecation of the accreditation schema, guiding future architectural decisions. Demonstrated a methodical approach to database design and management, balancing experimentation with disciplined code hygiene. The work emphasized clean repository practices and thoughtful change management, leveraging skills in SQL and database architecture throughout the process.
