About

Son of an programmer who could never quite get coding and instead made a career of being a lawyer who understands tech. With vibe coding, I've finally crossed the chasm and am thrilled with the possibilities. At work, I've built local and Backstage-hosted applications for use by in-house colleagues and thought deeply about build-versus-buy in the AI era. Outside of work, I've taught law students on advising tech product development teams, contributed to a book on the topic ("Advise, Innovate, and Inspire"), and am engaged with legal tech open source.

2 Projects

Gamified Self-Improvement to Enhance Tabular Review

Web AppOpen Access

As part of a project to build contract analysis tooling for a commercial legal team, I built out a method for non-Legal Quant team members to contribute to the improvement of the system in a fun and engaging way: a gamified interface for QAing the result of both AI and human-generated contract analysis. The output of this tool goes back into a tabular review system and, over time, increases the accuracy of the AI contract extractions. Built a tool for users of an internal tabular review system to either approve or disapprove of a human comparison to AI analysis done by a tabular reviewsystem. Demo video provided.

Internal Legal Suite of Tools

Web App

Built a tool to apply internal team proposals to legal team templates; conduct tabular review of a medium-volume set of contracts; and to do in-depth review of a single contract. Additionally/separately, built a command line interface high-volume contract analyzer to conduct a "portfolio-level" review of contracts for a company, effectively a contracts lifecycle management augmentation.

Philosophy

"Fancy demos are exciting, but true scaled adoption with quantifiable ROI is the real goal"

The marketing around AI and vibe coding is tremendous and exciting -- but I am forever hunting for verifiable examples of rock-solid use cases of widespread adoption. I've seen these internally at work but only in limited cases externally.

"Do not wait for a roasted pigeon to fly into your mouth"

This is a funny old quote that I think embodies the Legal Quants philosophy: there are high-value things available in the world, but you need to interact with or make them yourself if you want to their benefit to accrue to you. Don't just wait for someone else to do it for you.
