About

I'm a real estate attorney at a large US law firm. My clients acquire, build, manage operate and sell digital infrastructure. My interests in software development focus on developing tools to both accelerate and improve how lawyers represent their clients in transactional settings. I build tools that facilitate the strongest legal work product in collaboration with human attorneys rather than as a replacement.

Ambrose: AI-Powered Contract Review

Web AppSource

Ambrose is a collaborative AI contract review assistant built specifically for attorneys who need surgical precision, not wholesale rewrites. Unlike blunt AI tools that dump a wall of generic redlines, Ambrose breaks the review into phases — intake, risk analysis, clause-by-clause collaborative review, and finalization — so the attorney stays in control of every decision. It builds a complete risk map of the entire document, understanding how clauses interact across sections rather than treating each paragraph as an island. When a risk is identified, the attorney sees exactly what's wrong, why it matters, and can request a targeted revision that modifies only the specific language at issue. Attorneys can flag clauses for client discussion, filter and search by risk level, and navigate the document's conceptual structure — not just scroll through pages. The result is a polished Word document with track changes preserving the original formatting, plus a client transmittal email, ready to send without copying and pasting a single line.

SARA: The AI Senior Associate and Research Assistant

Web AppSource

Sara is an AI drop-in replacement for a senior law firm transactional associate. She can be granted skills for real estate, corporate, tech transactions, or any transactional practice, and she has guidance for how to create new skills. With a given skill enabled, she and a team of agents will review, comment on and thoroughly revise any contract based on a few basic instructions. She turns what could take 8+ hours of associate time into around 15 minutes with the highest quality output.
