OVERVIEW 01 / CLOUD & INFRASTRUCTURE

Infrastructure I can build, observe, and recover.

My infrastructure work spans Azure Stack support, AWS deployments, and Kubernetes operations. Today, I bring that experience into Terraform, GitOps, and my own computing environment. I care about the full lifecycle: how a system is provisioned, how changes reach it, how a failure becomes visible, and how it is recovered.

01

Infrastructure as code

I use Terraform to make cloud resources and container infrastructure easier to understand, reproduce, and change deliberately.

  • Terraform
  • OCI
  • Cloudflare
  • Docker
02

Kubernetes & delivery

I work with Kubernetes migrations and GitOps workflows, connecting configuration in Git to the systems it operates.

  • Kubernetes
  • FluxCD
  • GitHub Actions
  • Helm
03

Monitoring & recovery

I connect service health, logs, and metrics to practical operational decisions, with backup and recovery considered alongside deployment.

  • Grafana
  • Prometheus
  • Linux
  • Synology
04

Controlled operations

I choose update and access policies around a workload’s needs, from deliberate fleet changes to automatic container updates.

  • Johnaverse Fleet
  • Watchtower
  • Cloudflare Zero Trust
  • PowerShell

THE LOCAL SIDE OF THE CLOUD

A lab to build.
A place to learn.

Local compute and storage complement cloud services. This is where I explore model serving, infrastructure tooling, and recovery workflows.
