• Identified problematic queries and used execution plans, indexing strategies, and other techniques to improve their performance
• Partnered with engineers to improve database schemas, indexes, and query patterns as new features and services were developed
• Investigated a production database issue, identified the underlying cause, and implemented a longer-term fix to prevent it from recurring
• Automated routine database maintenance and operational work, reducing manual effort and making our systems easier to manage at scale
• Reviewed capacity and performance trends to anticipate future scaling needs and identify opportunities for infrastructure improvements
• Planned and executed database upgrades, migrations, and configuration changes while minimizing risk and customer impact
