A working repository of the things I'm building during the Gauntlet AI program. Healthcare, agentic systems, and the unglamorous infrastructure that holds them together.

Gauntlet AI is an intensive, full-time program for building real, production-grade software with AI as a first-class collaborator — each project below is shipped end-to-end on a tight clock, from architecture through deploy.

Projects

• Clinical Co-Pilot An OpenEMR-embedded agent for the 90-second pre-visit briefing. Reads from the chart, cites every claim back to a source record, and refuses to answer when it can't.
• CATS Copilot Automated Tactical Security — an adversarial multi-agent platform that continuously attacks the Clinical Co-Pilot. Plans campaigns, fires prompt-injection, PHI-exfiltration, and tool-abuse probes, judges the results, and files the confirmed exploits.
• Context Shield A secure context pipeline that sits between your documents and an external LLM: detect → obfuscate → call → restore. Raw PII, PHI, and privileged text never cross the trust boundary in readable form — but the model still gets enough structure to reason, and answers come back transparently restored.
• Meridian Non-custodial binary stock-outcome markets on Solana. Trade Yes/No tokens on whether a MAG7 stock closes above its strike today; the winning side redeems for $1.00 USDC. Collateral lives in a program-derived vault — correctness enforced by code, not by trust in an operator.
• Fraction Tutor A Synthesis-style conversational math tutor that teaches fraction equivalence to nine-year-olds. A warm, voiced tutor guides the child through an interactive chocolate-bar manipulative — splitting the same bar to discover the amount stays equal as the pieces multiply. Built for Safari on an iPad.
