At Tech Mahindra, I led an 800-server migration from Windows to Linux, using AWS EC2, S3, and Secrets Manager and implementing log shipping to maintain data consistency. I also coordinated database transfers, testing, and validation with infrastructure, storage, and network teams.

Previously, at Cloud Angles and HCL, I administered SQL Server environments, handled production backup, restore, and security issues, and managed database migrations and upgrades. My work has included high availability and disaster recovery, Always On troubleshooting, clustering, and Azure SQL migrations.
