Message

At Totale Biz Solutions Pte Ltd, I design hybrid and multi-cloud environments, infrastructure automation, and cloud security architectures aligned with business goals. My work includes Zero Trust models, policy enforcement, and security monitoring with Microsoft Sentinel.

At Ingram Micro, I advised customers on Azure, AWS, and GCP modernization and designed scalable landing zones. I developed Sentinel workbooks and KQL queries, and automated incident response with Playbooks and Logic Apps, reducing MTTR by 40%.

At Cognizant, I advised clients on Azure infrastructure and migration, architected secure landing zones, and developed DevSecOps pipelines with security scanning. I also designed AKS clusters and automation frameworks using Terraform and Ansible.

Earlier, I supported cloud infrastructure at Conduent and worked in Unix, high-availability clusters, and data-centre environments at IBM, Hewlett-Packard India Sales Pvt. Ltd (on behalf of Saggezza), and Cognizant. I hold Microsoft Azure Solutions Architect Expert and Microsoft Azure DevOps Engineer Expert certifications, among other Microsoft certifications.
