Johnny De Los Santos — Senior AI Solutions Architect

About Me

Senior AI Solutions Architect with expertise in cloud infrastructure, AI/ML systems, and production-grade automation. AWS Certified (Solutions Architect + Machine Learning Engineer) with hands-on experience designing Terraform-managed cloud platforms, GPU-accelerated AI inference pipelines, and enterprise DevOps workflows.

I architect systems that bridge AI capabilities with real-world infrastructure — from RunPod GPU clusters running LLM inference to AWS multi-region deployments with CI/CD. Beyond software, I bring a unique perspective as a digital fabrication specialist, operating MOPA fiber lasers and 4-axis CNC machines with custom automation tooling.

Featured Projects

Cloud Infrastructure (AWS)

Production multi-domain AWS infrastructure using Terraform. S3 origins with CloudFront CDN, OAC security, automated CI/CD via GitHub Actions OIDC, Route 53 DNS, and ACM certificates. Powers multiple live domains at ~$2-3/month with zero-downtime deployments.

Stack: Terraform, AWS (S3, CloudFront, Route 53, ACM, IAM), GitHub Actions OIDC

Infrastructure Code

AI Infrastructure Platform

GPU-accelerated AI inference infrastructure on RunPod with Terraform provisioning. Docker Compose orchestration: Ollama (LLM inference), Open WebUI (frontend), Nginx Proxy Manager (SSL/routing), and Authentik SSO (multi-tenant auth). Productized as AIaaS for clients.

Stack: Terraform, RunPod, Docker Compose, Ollama, Nginx, Authentik

Digital Fabrication Suite

Blender + CNC/laser integration with 4-axis machining workflows, MCP server for AI-assisted design, FabEx/BlenderCAM toolpath generation, and depth map processing for CNC relief carving. 150+ files spanning the full digital-to-physical pipeline.

Stack: Blender, Python, FreeCAD, GCode, LightBurn XML

Live Demos — Freedom Vault

Self-hosted AI infrastructure stack. Each subdomain below is a working capability surface from my Freedom Vault platform — local-first LLM inference (Ollama), generative imagery (ComfyUI), SSO (Authentik), and home automation. Inference is backed by a hybrid plane: local GPU + RunPod RTX A4000 burst capacity + OpenRouter fallback for premium models. Public access via private beta — request an invite link to use the gated live chat console.
