Hasan Ali

I’m a Senior DevOps Engineer and Site Reliability Engineer with 10+ years of experience building, automating, and supporting cloud infrastructure across AWS, Azure, and GCP. I specialize in designing scalable CI/CD pipelines, Kubernetes platforms, infrastructure as code, and observability solutions that improve reliability, security, and software delivery performance.

In my current role at Mondelez International, I manage and support a multi-region AWS environment across 12+ production accounts with 99.98% uptime. I led the migration of 200+ microservices to Amazon EKS using Terraform, Helm, and ArgoCD, built CI/CD pipelines with GitHub Actions and AWS CodePipeline, and reduced deployment failures by 65%.

I’ve also driven operational excellence through SRE practices—SLOs, SLIs, alerting standards, and incident response procedures—alongside clear cost optimization efforts like resource right-sizing and SpotInstance adoption (about $2.4M in annual savings). I integrate security and compliance controls into delivery workflows using tools such as Snyk, Trivy, Checkov, HashiCorp Vault, and AWS Secrets Manager.

Previously at Thoughtworks, I delivered DevOps and SRE transformation for Fortune 500 clients, improving reliability by 40%, reducing major outages, and increasing MTTR by 55%. I built GitOps-based deployment pipelines, established AWS multi-account landing zones with governance guardrails, and enforced security and resource policies across production Kubernetes clusters using operators and admission controllers.
