Concise monthly summary for 2025-03. In edx/configuration, delivered a safer and more reliable database maintenance capability: the Reliable Database Table Cleanup. The cleanup script now drops DOP tables in an order that respects foreign key constraints and skips tables with recent activity, preventing errors during maintenance and reducing downtime. This work improves data integrity during cleanup, lowers risk for production outages, and demonstrates proficiency with SQL scripting, constraint-aware logic, and maintenance automation.

February 2025 (edx/configuration): Implemented an automated stale-database table cleanup script to safely drop unused tables while preserving foreign key dependencies. The script supports a dry-run mode for safe validation, includes retries for AWS service interactions, and uses environment variables to manage database credentials for secure deployment. Delivered end-to-end with a single commit, enabling data hygiene improvements without disrupting active data flows. This work aligns with cost optimization, storage reduction, and operational resilience goals.
