Month: 2024-11 Concise monthly summary for performance review: - Key features delivered: Implemented the Automated Curriculum Data Import (Course & Section Catalog) feature for the uprm-inso4101-2024-2025-s1/semester-project-regiupr repository. The feature introduces web scraping and data processing to export course and section data from the university registrar into the database, enabling automatic population of curriculum information. - Major bugs fixed: No major bugs reported this month. Note: a manual integration step was performed to accommodate an auto-merge limitation, with the M2_Curriculum mods added to the database directory (commit referenced below). - Overall impact and accomplishments: Reduced manual data entry for curriculum data, improved data consistency across systems, and established a scalable ETL pathway to keep curriculum information up-to-date. This supports downstream processes such as scheduling, reporting, and analytics. - Technologies/skills demonstrated: Web scraping, data transformation/ETL, database integration, version control and merge workflow management, and repository-specific workflow for the semester project.
