DevOps engineer with six years of experience building and running deployment pipelines and cloud infrastructure for transaction-heavy web services.

Comfortable owning on-call, writing infrastructure as code and coaching developers on how their services behave in production.

- Own the CI/CD platform for 40 microservices on Amazon EKS, using GitHub Actions and Argo CD; deploy frequency rose from about five a week to more than twenty a day.

- Wrote SLOs and Prometheus alert rules with each service team, cutting pages outside business hours by roughly half over one year.

- Ran production for a B2B scheduling product on AWS ECS, holding availability above the contracted 99.9 percent for eleven consecutive quarters.
- Built the incident process from scratch, including on-call rotations, runbooks and blameless postmortems, and mean time to recovery fell from over two hours to under thirty minutes.
