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.

Synthetic Data Generator

2024

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.

Self-Hosted Knowledge Base & Automation

2024–present

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.

2023–present

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.

Price Transparency Data Lake

2018–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.

Federal Analytics Product in Palantir Foundry

2018–present

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.

Large-Scale Payment Simulation & Policy Modeling

2018–present

Claims-level simulation modeling for state government agencies evaluating changes to how they pay healthcare providers — the fiscal impact quantified before a policy goes live, not discovered after.
