Kai-Ming Chang

I’m a Platform/DevOps engineer with 5+ years spanning CI/CD, cloud infrastructure, backend services, SQL systems, and production reliability. I focus on delivery systems where infrastructure, release safety, and application behavior meet—so teams ship faster without sacrificing confidence.

In my current contract, I moved a startup from manual PoC setup to production-ready GCP delivery using Terraform, dev/prod separation, and CI/CD. I cut provisioning from 2+ hours to under 10 minutes and reduced deployment blast radius by replacing broad cloud access with identity-based CI auth, scoped secrets, isolated credentials, pinned dependencies, and PR quality gates.

Earlier, I improved release operations and runtime performance end-to-end. I reduced release preparation by 30+ minutes by keeping internal GitLab CE runners reliable on CentOS and improving Azure DevOps delivery for Windows-based C# projects. I also removed a recurring reporting bottleneck by moving SQL Server work out of application-layer processing, cutting runtime from 3 minutes to 4 seconds.

I’ve also maintained business-critical systems under real production constraints. In an ERP role, I supported 20+ monthly releases and reduced support risk by resolving 8+ critical incidents using C#, SQL debugging, query fixes, and legacy system upgrades. I continue building GitOps-managed platform projects on GCP with Terraform/OpenTofu, Kubernetes patterns, and workload identity to minimize credential risk.
