- Ensure databases meet SLAs for availability, performance, and recoverability through proactive monitoring, alerting, and capacity planning.
- Perform advanced troubleshooting of production incidents
- Drive root cause analysis (RCA) and implement preventative improvements to reduce repeat incidents.

- Manage database object permissions, role-based access, and secure connectivity.
- Operate databases in Azure and on‑prem infrastructure.
- Support cloud migration initiatives and hybrid architectures; advise on managed services vs. self‑managed database deployments.
- Improve platform resiliency and cost efficiency through right‑sizing and resource optimization.
- Build and maintain automation for routine DBA tasks (health checks, index/statistics maintenance, backups, patching support, reporting).
- Develop scripts and tools using languages such as Power Shell, Python, T‑SQL, PL/SQL, and scheduling/orchestration solutions.
- Enhance observability using database monitoring tools.
- Maintain clear documentation and runbooks for operational procedures, standards, and incident response.
- Provide guidance and mentoring to junior DBAs and technical teams.
