Platform Engineer

Building internal developer platforms that scale. Specialized in Kubernetes, GitOps, and API-centric architectures.

Currently building Hangar — an event-driven Internal Developer Platform combining Crossplane for control-plane provisioning, ArgoCD for GitOps delivery, Backstage for the UI, and AI-assisted workflows for operational intelligence.

The Hangar Ecosystem

  • hangar — IDP core, gitops strategy, and design docs
  • glidepath — CI/CD engine built on Tekton, PaC, and cosign
  • airframe — Crossplane XRDs and Compositions for infrastructure
  • apron — cluster provisioning templates and guardrails
  • tower — Backstage plugin for release orchestration and operational dashboards

Interests

  • Distributed systems and event-driven architecture
  • Infrastructure as code at scale
  • Security automation and compliance
  • Making infrastructure accessible to developers

Ask me about Crossplane functions, ArgoCD at scale, or why GitOps matters.
