Enterprise AI Architect | Multi-Cloud Platform Engineering | Production LLM Infrastructure
I build and ship enterprise AI systems at production scale — LLM infrastructure, RAG platforms, multi-agent systems, and multi-cloud Kubernetes platforms serving millions of users.
Over 12 years across financial services (Citibank, PCI-DSS payment infrastructure), retail (McDonald's, Chick-fil-A), healthcare, and highly regulated enterprise environments. I take complex, high-stakes systems from concept to production fast, with security and compliance built in from day one.
- Production AI: Vision-LLM document processing pipelines (95% faster, 99.5% accuracy), Gemini-on-Vertex AI advisory applications, RAG systems, multi-agent platforms
- MCP Ecosystem: Building MCP servers (aws-sage-mcp, gemini-image MCP) and agent security tooling (AgentMesh-Bench: 60,000+ adversarial attacks)
- Multi-Cloud Platforms: Kubernetes at 20,000+ container scale across AWS, Google Cloud, and Azure
- AI Security Research: Published in peer-reviewed journals (JCSTS) and IEEE CLOUD 2026 on AI agent supply-chain security
Sole architect and builder of an enterprise Gemini-on-Vertex AI application serving 500+ program teams. Reduced a 30-day cross-functional review process to under 5 minutes. Prototype to production in under 60 days.
Built AI document processing pipeline using vision LLMs — 95% timeline reduction, 99.5% accuracy, handling handwriting and rotated documents. MVP to production in under 60 days.
91.34% blind provider-fraud detection across 33,000+ providers using behavioral signals and Neo4j evidence graphs. Won 2nd place at a national hackathon.
Creator and lead architect of the largest enterprise Kubernetes platform-as-a-Service — 20,000+ containers across 20 clusters, 150+ teams, 700+ applications, 100% uptime, zero breaches. Software Factory pattern with 50+ Terraform modules and 50+ Helm charts.
Production multi-agent platform orchestrating Claude, Codex, Gemini, and Copilot for native iOS, macOS, and web clients. Single gateway, PTY shells, tasks, meetings, tracing.
Cloud solutions architect for Citibank (PCI-DSS, fraud detection, real-time event streaming), McDonald's, Chick-fil-A, American Heart Association (HIPAA), Ditech Mortgage, and Ellucian. 25% operating cost reduction, 60% fewer production risk alerts.
