Cloud & Infrastructure Engineer at LTIMindtree resolving complex Active Directory issues across enterprise environments.

India

Message

At LTIMindtree, I resolve complex Windows Active Directory incidents for enterprise clients, including issues involving AD Replication, DFSR, PKI, and Kerberos. I also write troubleshooting documentation and runbooks for AD and PKI.

Previously, at Concentrix, I diagnosed Active Directory issues and supported identity services across client environments. I also collaborated with engineering teams on preventive fixes and mentored junior support staff.

At Arvee Bizpro Solutions, I delivered customer-facing Active Directory support for Microsoft, troubleshooting virtual machines and supporting domain controller replication and PKI operations. My earlier roles at Quatrro Global Services and Convergys India Pvt Ltd included resolving Windows and Mac OS issues and configuring workstations.
