I’ve spent 9 years in cloud infrastructure engineering, CI/CD automation, resilience engineering, and large-scale distributed systems, delivering measurable improvements at Twilio and Stripe.

At Twilio, I architected multi-cloud infrastructure (AWS, Azure) for global messaging and Segment data platforms to achieve 99.99% availability during peak events. I led Kubernetes (EKS/AKS) migrations using GitOps (ArgoCD) and Helm, cutting release cycle times by 40% with zero-downtime deployments, while building secure pipelines with Jenkins/GitHub Actions, Snyk/Aqua scanning, and Vault-based secret management. I also designed event pipelines and observability stacks (Kafka, Lambda, Prometheus, Grafana, Datadog), reducing incident response times by 40% and scaling data sync capacity by 400%, alongside Infrastructure as Code (Terraform, CloudFormation) that reduced cloud spend by 15% during off-peak periods.

Beyond day-to-day operations, I led reliability and modernization initiatives—ensuring 99.99% availability for Segment ingestion at hyperscale, applying the Strangler Fig pattern to decompose legacy services with Orkes, and scaling data workflows to support enterprise integration. I’m driven by automation, strong observability, and secure delivery practices that reduce operational risk without slowing teams down.
