Summary
I'm a Senior Azure DevOps Engineer with 12+ years of experience designing, automating, and operating scalable cloud platforms on Microsoft Azure. I specialize in building end-to-end CI/CD pipelines, managing infrastructure using Terraform (IaC), and supporting containerized workloads with Docker and Kubernetes. My focus is on reliability, security, and speed - ensuring engineering teams can ship confidently and efficiently. On the operations side, I've implemented production-grade monitoring and observability using Prometheus and Grafana, helping teams reduce MTTR, improve alerting accuracy, and gain real-time visibility into Azure and AKS environments. I've led initiatives that: Reduced deployment times by up to 60% through CI/CD optimization Lowered cloud costs by 25% via infrastructure standardization and rightsizing Improved system reliability and incident response through proactive monitoring and automation I'm most effective in environments where I can own DevOps platforms, collaborate closely with engineering teams, and mentor others on best practices around cloud, automation, and operational excellence. Core skills: Azure DevOps, Terraform, CI/CD, Kubernetes, Docker, Prometheus, Grafana, Python Open to: Senior Azure DevOps Engineer / Platform Engineer roles
