Database Administrator

Chicago, IL · w.zhang@email.com · (555) 528-6013

Dear Hiring Manager,

I'm writing to apply for the Database Administrator role on your data infrastructure team. I currently maintain 99.99% uptime across 45 production SQL Server and PostgreSQL instances that support roughly 3TB of transactional data.

I led a query-optimization project that rewrote our worst-performing stored procedures, cutting average report generation time from 40 seconds to under 4. I manage nightly backups, log shipping, and a failover cluster with a recovery point objective under 5 minutes, and I recently completed a zero-downtime migration from SQL Server 2016 to 2022.

I understand your platform handles high-volume transactional workloads during peak shopping periods, which is exactly the kind of pressure I've built my tuning and HA experience around. I'd welcome the chance to discuss how I can help keep your databases fast and resilient.

Sincerely,

Wei Zhang
