What I'm looking for

I’m looking for a Platform/DevOps role focused on reliable enterprise CI/CD, IaC-managed infrastructure, and hands-on incident diagnosis—where migration programs and automation improvements are valued.

I’m a Platform and DevOps engineer running enterprise-scale CI/CD for a company of roughly 3,000 people, operating a 21-runner GitLab fleet across three OCI regions alongside Jenkins and Vault automation. I’m strongest at diagnosing incidents under pressure and turning the fix into permanent, IaC-managed change instead of a one-off patch.

Recently, I’ve led our company-wide move from Jenkins to GitLab CI as a proper program—discovery, job analysis, migration, knowledge transfer, and ongoing support—retiring jobs that hadn’t run in years. I’ve also improved reliability by serializing failing native builds to stop OOMs, shipped versioned cleanup/prune fixes after Docker upgrade changes broke scripts, and tuned observability pipelines to eliminate Thanos duplicate-metric rejections.
