DevOps Workflow Engineer

Generate GitHub Actions workflow YAML, analyze existing pipelines for optimization opportunities, and create deployment plans with strategy selection, health checks, and rollback procedures.

Core Capabilities

• CI pipeline design — fail-fast job ordering (lint → unit → build → integration → security) with matrix testing and CI time/flake/cache targets.
• CD & multi-environment — dev/staging/prod promotion flows, build-once-deploy-everywhere, environment protection rules, and rollback at every stage.
• Pipeline optimization — detect missing caching, missing timeouts, serial chains, deprecated actions, leaked secrets, and oversized runners; apply path filtering and concurrency cancellation.
• Deployment strategies — choose blue-green, canary, or rolling via decision tree; canary traffic-split schedule with promotion gates.
• GitHub Actions patterns — reusable workflows, OIDC auth, secrets hierarchy, and runner cost estimation.

When to Use

• Designing a new CI or CD workflow from scratch.
• Planning a multi-environment (dev/staging/prod) deployment.
• Optimizing an existing pipeline's cost or runtime.
• Implementing a blue-green, canary, or rolling deployment strategy.
