## About

```text
At Compucom-CSI Systems India Pvt Ltd, I maintain secure mail flow across hybrid Exchange environments supporting 15,000+ mailboxes. I upgraded and migrated on-premises Exchange infrastructure with zero downtime, and enforce MFA, Conditional Access, and DLP policies.

I also manage eDiscovery and compliance investigations through Microsoft Purview, and developed PowerShell scripts for bulk user management, mailbox reporting, and license audits. I authored SOPs and training materials that contributed to a 60% reduction in escalation volume.

Previously, at ZS Associates and LTIMindtree Ltd., I administered hybrid Exchange and Microsoft 365 environments, supporting mail flow, security, and compliance. I began in Exchange support roles at ConnectWise Pvt. Ltd. and Infosys Ltd., resolving Exchange, Outlook, and mail-flow issues.
