What I'm looking for

I’m looking for a role where I can own CI/CD and test infrastructure end-to-end—building fast, reliable pipelines and developer feedback loops that help teams ship confidently.

I’m a Senior Software Engineer with 8+ years building the infrastructure other engineers depend on: CI/CD pipelines, containerized build and test platforms, and the feedback tooling around them. At Juniper Networks (HPE), I’ve been the sole owner of test and CI infrastructure for a production network-assurance product.

I cut pipeline runtime by 70% by re-architecting test execution with pytest-xdist and Docker-based parallel workers, shrinking suite time from 2h40m to 45m. I also own Jenkins gatekeeping for every change, including merge-request validation hooks and OpenAPI-spec-driven coverage analysis to surface untested endpoints as a tracked metric.

I modernized legacy Selenium suites to Playwright and improved contributor onboarding by standardizing Python tooling and dependency management. I also designed and shipped a six-agent GitHub Copilot system for automated test authoring and self-healing, reducing time to author new test suites.
