👋 Hi, I'm Rex

🧠 Strategic Technologist · Cloud Architect · GenAI Engineer · Veteran

Welcome. I’m a battle-tested engineer and hands-on architect with 25+ years of diverse industry experience—ranging from public safety to banking, from government to AI-native platforms. I specialize in building autonomous, secure, and scalable systems at the intersection of Cloud, AI, Automation, and Developer Enablement.


⚙️ Focus Areas

  • 🔄 Cloud Automation & Infrastructure-as-Code
    Building GitOps-driven, modular infrastructure with Terraform, Packer, and Vault—automating every stage from provisioning to decommissioning.

  • 🧠 AI/GenAI Systems
    Architecting cloud-agnostic, AI-native multi-agent platforms using action languages, LLMOps workflows, and digital twin knowledge graphs.
    Designing agent ecosystems powered by foundation models, semantic memory, and reasoning engines for real-time decision-making.
    Integrating vector search, prompt orchestration, and domain-specific inference to enable scalable, autonomous intelligence.

  • 🧰 Self-Service Platform Engineering
    Enabling developers with Terraform-based frameworks, feature flagging (ie, FlagSmith, ConfigCat, Split.io), and Backstage-style portals for zero-friction provisioning and deployment.

  • Serverless Application Development
    Architecting event-driven systems using Lambda, API Gateway, Azure Functions, and container-native FaaS runtimes—optimized for speed, scale, and cost-efficiency.

  • 🧱 Container OS & Runtime Innovation
    Creator of SysSpace, a minimalist container-native OS designed for next-gen workloads beyond Linux.

  • ☁️ Cloud Architecture & Engineering
    Designing resilient, secure, and scalable cloud architectures across AWS, Azure, GCP, Oracle, IBM, Alibaba, Tencent, and hybrid environments.

  • 🚦 Cloud SRE & Observability
    Embedding reliability through OpenTelemetry, automated rollback hooks, cross-platform secrets rotation, and proactive alerting using native observability tools across AWS, Azure, GCP, and beyond.


📚 Philosophy

Read more in my operating model

I don’t preach best practices—I build them, battle-test them, and leave behind engineers who can outdo me.

I’ve led high-stakes transformations where fragile, manual processes became hardened delivery systems—driven by Infrastructure-as-Code, GitHub Actions, intelligent gating, and container-first design.

  • I’ve replaced ticket queues with self-service Terraform frameworks.
  • I’ve embedded observability from the first commit using OpenTelemetry.
  • I’ve secured entire workloads with Vault, Snyk, and automated policy checks.
  • I’ve empowered engineers to move fast without breaking things—through developer starter kits, blue/green deploys, and feature flag-driven experimentation.

My philosophy is simple:

Set the standard. Codify it. Enable others to surpass it.
