What I'm looking for

I'm seeking a responsible and challenging position where I can apply my skills and dedication, grow with the organization, and pursue a rewarding career working with the latest technologies.

At Sonata Software, I work on an IMS Support project across global hybrid deployments, supporting servers, workstations, printers, and other IT equipment. I design and build technology services on-premises, in the cloud, and on SaaS platforms.

I work with the Microsoft 365 suite, including Entra ID, Exchange Online, Defender XDR, Teams, and SharePoint. I also manage customer resources and billing, while maintaining infrastructure uptime in line with defined SLAs and OLAs.

At OSI Digital, I joined as a Windows Server Administrator providing L2 support in Azure Managed Services and was promoted to L3 Architect. I managed on-premises, virtual, and cloud-hosted infrastructure, including Azure migrations, VM deployments, performance monitoring, and vulnerability remediation.

Earlier, at Cognizant, I handled incident and identity access management for a US client and used Windows Server, Exchange, Skype for Business, PowerShell, and OIM. My experience also includes desktop and field support at Capgemini, Apex Services, and HCL Infosystems. I hold MCSA in Server 2012, ITIL v3 Foundation, AZ-900, AZ-104, and SC-100 certifications.
