Johnathan Horner

FOUNDER / AI SOLUTIONS ARCHITECT

• Shipped 8 production AI systems on AWS using modern RAG architectures (Agentic, Multimodal, Hybrid, Corrective) — including ConnectIQ (AI-powered call center SaaS) and @johnathan-horner/cdk-ai-constructs (published npm CDK construct library) — across financial services, healthcare, education, and government
• Built MCP servers with FastMCP that expose tools, resources, and workflow prompts so AI assistants connect to backend systems without manual handoffs
• Set up CI/CD with GitHub Actions, documented all FastAPI endpoints with OpenAPI, wrote model cards for every ML model, and recorded architecture decisions for every service selection
• Built a real-time fraud detection system: PyTorch autoencoder scores transactions via Kinesis streaming, flagged transactions go to a 4-node LangGraph investigation agent on Bedrock Claude, full SR 11-7 / SR 26-2 governance with PSI drift monitoring
• Built a medical image triage system: TensorFlow EfficientNetB0 classifies images and routes to physicians based on confidence (above 0.9 auto-triage, 0.7-0.9 expedited, below 0.7 senior review), HIPAA-compliant audit trail
• Built a legal document classifier: fine-tuned DistilBERT handles classification at 10K docs/day, three parallel LangGraph agents analyze clauses, check regulatory compliance, and generate attorney briefings, FedRAMP-aligned
• Launched ShootItPicks (shootitpicks.com) as a revenue-generating SaaS with Stripe billing, a 5-step Chain of Thought AI pipeline, Monte Carlo CVaR risk engine running 10K simulations, and an MRM calibration layer that corrects model confidence against real historical accuracy
