And keep them running.

I work across cloud infrastructure, release pipelines, and production.

  • Cloud infrastructure

    Choosing and configuring the cloud services each application needs to run.

  • Deployment automation

    Setting up automated build, test, and release pipelines so deployments are consistent and repeatable.

  • Production reliability

    Monitoring applications, investigating issues, and keeping systems running reliably after launch.
