TCPA Litigation Explorer

A case study in zero-backend analytics. After Facebook v. Duguid redrew the ATDS boundary, tracking post-2021 TCPA litigation trends required a new tool. Built on MotherDuck Dives and an MCP-driven build loop, then published as a static site running DuckDB-WASM in the browser — 29K rows, no backend, no account required.

Film Scrubber

A sports film viewing webapp I created, modeling the functionality off of football film clickers I used during my days working in football. The app allows a user to easily scrub through a YouTube video and watch back their play from their sport of choice. The app was created to test out the functionality of Claude 4.6.
