Jay Chen

I've built production cloud infrastructure and platform automation for Atlassian, Datadog, HashiCorp, and Twilio. At Atlassian, I architect AWS foundations and Terraform modules that standardize networking, IAM, databases, and container infrastructure across SaaS environments.

I rebuilt CI/CD gates around immutable artifacts, health checks, progressive rollouts, and automated validation, reducing deployment rollback frequency by 34%. I also established observability standards across metrics, logs, and traces, cutting non-actionable alerts by 41%.

At Datadog, I improved incident recovery time by 29% through stronger dashboards, ownership metadata, runbooks, and deployment-to-infrastructure signal correlation. At HashiCorp and Twilio, I developed Go and Python automation, Terraform modules, Kubernetes deployment workflows, and safer infrastructure testing practices.

I enjoy turning recurring reliability, security, and operational problems into reusable tooling, practical runbooks, and better platform defaults. I've mentored engineers through infrastructure reviews, blameless post-mortems, and cost investigations while helping teams ship safely.
