I founded and operated ZONA, a two-sided consumer marketplace, owning pricing, venue partnerships, retention, and growth end to end. I work in SQL and Python to find what's actually happening in a business, then ship the fix: a pricing change, an operating process, or, when it's the right tool, an AI system.
Marketplace Pricing & Promotion Simulator · Live app A contribution-margin decision simulator built on 824K real transaction line items to stress-test take rate, fulfillment cost, promotional investment, and demand assumptions, including a promo breakeven calculator and a lever sensitivity ranking, so the tool identifies which economic lever moves marketplace profitability the most, not just what happens when you move a slider. Python, pandas, Streamlit, Plotly.
Sentra · Live demo Autonomous AI agents can take real actions (sending messages, approving records) before anyone checks if they should. A runtime policy layer that scores every proposed agent action and blocks, allows, or escalates it before it executes, with cumulative risk tracking and a three-strike shutdown. Demonstrates: governance, risk-based decision rules, systems thinking. Python.
Sentra Medication · Live demo Independent runtime governance for AI-assisted medication management, adapted from Sentra. Intercepts every AI-generated medication order, validates it against live patient data via FHIR R4, and returns allow/block/escalate before the order reaches the pharmacy, with an EU AI Act Article-12-shaped audit log. NYU SPS Berlin GFI 2026 team project, presented to Google and Join Capital, won the final pitch. Demonstrates: healthcare AI governance, regulatory-grade auditability, team leadership. Python.
Nonprofit Financial Health Dashboard · Live app Is this organization's financial position getting stronger or weaker, and where's the risk? Real IRS Form 990 filings for 20 nonprofits, EIN-verified against known values at fetch time, with illustrative (adjustable) screening thresholds and peer comparisons that suppress themselves when a sector's sample is too small to mean anything. Demonstrates: financial-statement analysis, risk screening, data-integrity discipline. Python, pandas, Streamlit, Plotly.
Healthcare Access Risk Analysis · Live demo Where should limited access-to-care resources go first? A composite risk-scoring model across county-level population, insurance, and hospital-density inputs, ranking and mapping 3,200+ counties into priority tiers. Demonstrates: geographic prioritization, weighted decision modeling. Python.
Medicare Billing Analysis Hospital pricing for the same procedure can vary 3x+ by location. SQL analysis of CMS Medicare billing data (145K+ records, 3,000+ hospitals) to find cost outliers, markup patterns, and geographic pricing disparities. Demonstrates: SQL, pricing-variance analysis, geographic economics. SQL.

I use code when it's the fastest way to test the hypothesis or operationalize the answer.
