Principal DevOps Engineer · Platform Engineering · AI

Infrastructure should build itself.

I build platforms that manage themselves and write about what AI actually changes in DevOps.

  • Self-operating platforms with GitOps and automation
  • AI in DevOps, from pipeline generation to deployment triage
  • Platform engineering, cloud infra, and the tools I actually use
  • Everything built in public, homelab to production

Projects

K3s Homelab Cluster

LIVE

Kubernetes on a Raspberry Pi 5 cluster, managed entirely through FluxCD. Automated TLS with cert-manager, network segmented via Ubiquiti VLANs.

  • Push to main, FluxCD reconciles within 60 seconds. No manual deploys.
  • TLS certificates rotate automatically through Let's Encrypt and cert-manager
  • Separate VLANs for IoT, lab, and management traffic

GitOps Platform Engine

ACTIVE

Every feature branch gets its own isolated environment via Azure DevOps Pipelines. Environments spin up on push and tear down on merge.

  • Branch-based environments with automatic provisioning and teardown
  • Azure Workload Identity federation, so zero credentials live in pipelines
  • Helm chart templating with per-environment value overlays

AI Pipeline Orchestrator

ACTIVE

Claude Code generates pipeline configs, reviews Helm charts, and triages deployment failures. An automation layer for the repetitive parts of infrastructure work.

  • Pipeline YAML generated with org-specific conventions baked in
  • Helm chart review that catches misconfigs before they reach staging
  • Deployment failure triage with fix suggestions pulled from build logs

Infrastructure testing — why your Terraform plan is not a test

Terraform plan tells you what will change. It doesn't tell you if the change is correct. Real infrastructure testing requires real assertions.

Azure DevOps Pipelines — the parts they don't document

The official docs cover the happy path. Here's what I learned from the edge cases: conditional stages, variable group scoping, and service connection gotchas.

The CI/CD pipeline nobody maintains — why pipeline-as-code needs ownership

Pipeline YAML is code. It has bugs, tech debt, and dependencies. But nobody owns it, so it rots in place until something breaks at 2 AM.

Got a project in mind?

I'm always up for a good conversation about platforms, automation, or DevOps. Book a call.
