• Implement archiving solutions and lifecycle management for data retention.
• Analyze and document database infrastructure, hardware, and technology requirements.
• Partner with development teams to review code and design for performance, scalability, and alignment with best practices.
• Provide expert-level troubleshooting and root cause analysis for database-related incidents.
• Mentor development and data warehouse teams on advanced SQL, PL/SQL, and MongoDB query optimization.
• Continually improve DBA standards, procedures, and automation practices.
