Cloud Engineer

Cloud Engineer with hands-on experience managing end-to-end Azure infrastructure in hybrid environments. I specialize in designing and operating secure, scalable, and cost-optimized cloud solutions across compute, storage, networking, AI, and identity. I’ve led critical initiatives such as AKS version upgrades in production, built AI pipelines using Azure AI Studio, and enforced enterprise-grade security using Defender for Cloud, RBAC, and Conditional Access. My work spans provisioning and automation of VMs, AKS, AVD, and storage; implementing Synapse pipelines; managing Intune and Zero Trust policies; and optimizing costs through Reserved Instances and Azure Advisor. With a strong focus on operational excellence, I bring a balance of deep technical execution and strategic alignment to business needs-ensuring performance, compliance, and resilience across the cloud landscape.
