Featured work

  1. Fantasy Edge

    Shipped

    A browser-based research tool that blends Yahoo Fantasy rosters with Statcast metrics, Pitcher List rankings, and aggregated prospect lists. Every query runs client-side in DuckDB WASM, so there is no backend to host. It turns four scattered sources into one roster decision.

  2. copilot-bootstrap

    Exploration

    A CLI that scaffolds a new project with opinionated boilerplate, configuration defaults, and generated documentation. It uses GitHub Copilot to fill the parts that change per project. The goal is a first commit that already passes lint and CI.
