Leading Infrastructure Projects Worth $30M+ | AI/ML Platform Specialist

Architecting and delivering mission-critical cloud infrastructure, from directing a $30M United Airlines infrastructure program to leading AWS migrations for Delta Airlines. Passionate about building scalable, observable, and secure systems that power the next generation of AI and enterprise applications.


🛠️ Technical Expertise

🤖 AI/ML Infrastructure & Platform Engineering

  • GPU Virtualization & Passthrough: Proxmox GPU passthrough and vGPU configuration for hardware acceleration.
  • AI Inference Systems: Self-hosted GPU-accelerated LLM inference platforms (using llama.cpp and optimized quantized models).
  • Container Orchestration: Deploying high-performance Kubernetes nodes for stateless services and data-intensive workloads.
  • Full Observability: Real-time metrics collection and dashboards (Prometheus, Grafana, Zabbix) for hardware health, latency, and throughput.

⚙️ DevOps & Cloud Automation

  • Infrastructure as Code (IaC): Writing modular, reusable Terraform modules and Ansible playbooks.
  • CI/CD Pipelines: Automated deployments, automated testing, and zero-downtime release workflows using GitHub Actions and Azure DevOps.
  • Virtualization Clusters: Multi-node high-availability Proxmox VE clustering, LXC containerization, and custom storage setups (ZFS).

🛡️ Network Engineering & Zero Trust

  • Enterprise Networking: Hybrid-cloud architectures, firewalls, VLAN segmentation, and UniFi deployment.
  • Secure Remote Access: Zero Trust networks configured via Cloudflare Tunnel, WARP Gateway, and Tailscale.
  • Modern DNS Infrastructure: High-availability Technitium DNS clusters with split-horizon configurations and automated DNS-level ad blocking.
