Projects

A mix of client work I can describe only in general terms, and personal projects I can show in full: pipelines, a self-hosted game, and infrastructure built for no reason other than wanting it to exist.

Annual Inpatient Hospital Rate Setting & Policy Simulation

2025-2026

A claim-level rate-setting pipeline and four-scenario policy simulation using two years of inpatient claims to update hospital payment rates, quantify provider-level tradeoffs, and support selection of a model affecting roughly $148 million in modeled payments.

Synthetic Data Generator

2026

A four-stage pipeline that generates privacy-safe synthetic datasets, preserving cross-column statistical correlation, for testing in a locked-down environment where production data never leaves the room.

Price Transparency Data Lake

2023–present

A data lake and automated pipelines ingesting machine-readable pricing files from 80+ healthcare payers under the federal Transparency in Coverage Act, externally-published data at volume, with automated quality monitoring replacing manual review.

Supplemental Payment Program & UPL Demonstration Development

2018–present

Provider-level payment modeling and Upper Payment Limit demonstrations for state Medicaid supplemental payment programs supporting over $95M in annual payments, built to withstand CMS review and absorb new participating providers without a methodology redesign.

Self-Hosted Knowledge Base & Automation

2026

A self-hosted personal knowledge base with six automated workflows, including a scoped Claude Code agent that reviews and proposes edits to the knowledge base itself every week, reachable only through a private mesh network, never the open internet.

2026

A self-hosted MUD built on Evennia: game design, backend, deployment, and networking all owned end to end, with puzzle design prioritized over grinding mechanics.

Federal Analytics Product in Palantir Foundry

2022–2023

Technical lead delivering demographic and geographic analysis of social drivers of health for a US federal agency, built inside the agency's own Palantir Foundry environment so it shipped as a living product, not a one-off deliverable.

Medicare Crossover "Lesser-Of" Payment Policy Simulation

2026

Claim-level fiscal impact modeling for a proposed Medicaid policy limiting Medicare crossover payments to the lesser of the fee schedule amount or beneficiary cost-sharing liability: $46M in estimated annual savings, quantified before the policy went live.

Rural Provider Gap Analysis & Analytics Platform

2026

A multi-source analytics platform unifying Medicaid, Medicare, and commercial claims with provider, census, and workforce data to evaluate rural healthcare access and specialty shortages statewide.

Rural Obstetric Service Resumption Payment Modeling

2026

A provider-level payment simulation estimating roughly $3.1 million in combined potential annual reimbursement if four rural hospitals resumed obstetric services, giving a Medicaid agency quantified financial incentives to encourage restoration of rural maternity care.
