Primary owner for Oracle database backup and recovery modules. My work involves enhancing the product with new features as per customer requirements, maintaining and refactoring legacy modules, triaging and patching bugs, improving sql performance. Key Projects: 1. Behavioral Anomaly detection for databases - End to end ownership for anomaly detection in databases like GCP BigQuery, PostGreSQL, MySQL using algorithmic analysis of time series data. 2. Distributed GCP Firestore workload - Architected a scalable and distributed design to backup and restore GCP firestore databases. - This includes dump based full backups and detecting changes on documents in a collection to perform incremental backups. - Reliable recovery of the backups in disaster scenarios and scalable design to ensure optimal performance for databases with size in TBs. 3. Snapshot v2 An incremental improvement of Block level Snap Backup design for cloud native Oracle databases to optimize storage costs for customers.

4. Enhanced Deduplication for TDE encrypted databases - Performed structured deep dive on block level packet structure of oracle generated backup-pieces for TDE encrypted databases. - Redesign of block level realignment design to improve deduplication which was critical in improving performance of backups and reducing storage costs by ~40% 5. Incremental SQL Schema enhancements - Worked on improving the schema design for the SQL server tables to reduce bloating and improve performance of the SQL server by ~15% - Rewrote queries to optimize performance by understanding database internals reducing query execution time by 50 minutes 6. Triaging framework for Oracle issues - Architected an escalation triaging framework that performs initial triaging steps for known issues and provides the initial analysis of the issue and reducing engineering time spent by ~80% - Currently working on enhancements to integrate this framework prior to the issue being notices providing early detection 7. Contributed to key product enhancements for Oracle databases on local disk and storage arrays - Replication using Dataguard - PDB Clone - Table level restores 8. Critical Customer Issues and POCs Resolved 50+ customer tickets and assisted multiple customer POCs clearing roadblocks on live-sessions. - Exposure to enterprise scale database management, performance issues and critical problem solving ability to mitigate customer concerns
