Who is behind the work

Virginia, USA · Remote worldwide

Consultant & Platform Engineer specializing in Cloud Infrastructure, Linux, Automation, and Kubernetes. I design, deploy, and support secure, scalable platforms across AWS and Azure, using Infrastructure as Code, automation, and modern DevOps practices. I'm passionate about solving complex technical problems, building reliable infrastructure, and helping teams turn technology into practical business solutions.

how I work

Three rules I keep

  • 01

    Design before deploy

    Every environment starts as a written design: network zones, identity, naming, backup and patching, agreed before the first resource exists.

  • 02

    Automate the second time

    Anything done twice becomes code. Terraform and Ansible are how a platform stays the same on Friday as it was on Monday.

  • 03

    Document the handover

    A platform is finished when the team running it has the runbook, the diagram and the person to call. That is part of the work, not an extra.

at a glance

One platform, many moving parts

Linux at the center, with containers, the three major clouds and infrastructure as code around it. Each link is something I design, build and support.

what I do

Platforms, end to end

Design, build, secure and support. The same person from the architecture document to the on-call handover.

    Cloud infrastructure

    Design, provision and support platforms on AWS and Azure with Infrastructure as Code, so environments are repeatable and auditable.

    • VPCs and VNets, DNS, IAM, storage and compute laid out from a written design
    • Terraform for provisioning, GitHub Actions for validation and deployment
    • Security models and documentation that survive the handover

    Linux and automation

    Enterprise Linux run as a managed fleet: standard builds, patch windows, hardening and configuration kept in code.

    • RHEL, Rocky and Ubuntu builds from standard images and hardened baselines
    • Ansible roles and shell automation for configuration, patching and drift remediation
    • SELinux kept enforcing, with denials diagnosed rather than switched off

    Kubernetes and platforms

    Container platforms and data-science tooling deployed, secured and kept observable, on managed Kubernetes or on VMs.

    • EKS, AKS and GKE clusters with Docker-based workloads and clear ownership
    • Posit Team (Workbench, Connect, Package Manager) on cloud and on premises

    • Custom, responsive sites in Astro, React and Tailwind CSS with light and dark themes
    • Accessibility, SEO and performance treated as requirements, not extras
    • Hosting, domain, DNS and email set up and documented so the owner stays in control

Two ways to start. Both run on Google Meet, times shown in your timezone.

Discovery consultation

30 min · Free

Tell me about your platform and get a straight opinion on the next step.

  • Where your platform is today and what is getting in the way
  • A straight opinion on the next step, with no obligation
  • Whether a working session or a longer engagement makes sense

Working session

60 min · $100

Architecture review, troubleshooting, or an implementation plan, live.

  • Architecture review of an AWS, Azure, Linux or Kubernetes platform
  • Live troubleshooting of a production issue, with the root cause explained
  • An implementation plan you can hand to your team

Both calls run on Google Meet. Prices in USD. A quick check confirms you are a person before the calendar opens.
