Borja Sanchez developed the Quarterly Admin Statistics Reports feature for the chamilo/chamilo-lms repository, enabling administrators to generate detailed quarterly insights into user activity, course engagement, training hours, certificates, and session durations. He focused on backend development using PHP and SQL, implementing data aggregation and partitioning logic to support robust historical reporting. By integrating this feature into the existing admin statistics page, Borja streamlined the reporting process and reduced manual effort for administrators. His work enhanced data analysis and reporting capabilities, providing more granular visibility into key metrics and supporting data-driven decision-making for program governance and compliance within the platform.
