  ┌─ SUMMARY ────────────────────────────────────────────────────────────────────────────────────┐

    Platform / DevOps engineer working across the full stack of modern infrastructure:
    CI/CD pipelines, Docker, Kubernetes cluster management, IaC-driven deployments.
    Builds and maintains internal tools and customer-facing applications end-to-end.
    SME for hands-on technical training content covering networking, automation,
    cloud-native platforms, and AI. Achieved Kubestronaut in 2024, awarded for holding
    all five Linux Foundation Kubernetes certifications at once. Currently digging
    deeper into cloud-native platform work and where AI fits into real engineering
    workflows.

    " If something can be automated, it should be. I get things done,
      figure out the rest along the way, and keep building. "
