@arifhasanhamanulla
Senior Azure DevOps Engineer specializing in Terraform/IaC, CI/CD, AKS orchestration, and cost-optimized Azure infrastructure.
CanadaWhat I'm looking for
I’m a Senior Azure DevOps Engineer with 10+ years of IT experience and 6 years focused on architecting and managing enterprise-grade Azure cloud infrastructure. I champion Infrastructure as Code, using Terraform and authoring complex Azure Resource Manager (ARM) templates to deliver secure, immutable, versioned, and auditable environments.
I design and implement end-to-end CI/CD pipelines with Azure DevOps, and I orchestrate containerized applications on Azure Kubernetes Service (AKS) to improve scalability and resilience for high-traffic workloads. I’ve delivered measurable outcomes—cutting monthly cloud spend by about $4,500 through automated cleanup and rightsizing, reducing environment setup time by nearly 40% (and ~70% in prior work), and improving availability by building high-availability architectures with Azure Site Recovery and Azure Load Balancers, supported by Azure Monitor, Log Analytics, and Application Insights.
