About

Lead Product Manager in New York.

I build AI agents and financial infrastructure for complex, high-stakes workflows. Lead PM at Quantile (LSEG), shipping production agents and 0→1 products used by global banks. The work has cut expert workflows from hours to minutes, scaled operations without added headcount, and generated $XM+ in new and expansion ARR.

Previously I originated a pre-trade margin simulator at OpenGamma. I trained in markets where precision is not optional, then brought that standard to agents.

I want to do this next at AI-native startups or in big tech, on teams that treat product craft as a competitive advantage. My deepest domain expertise is in fintech, and I am open to hard applications of AI in any domain. If you are working on one, get in touch.

02Plain terms

The ideas behind the work, in plain English.

Derivatives and agent systems come with jargon. These are the terms my case studies lean on, one line each.

Notional
The face amount a derivative is written on, not the money at risk.
Compression
Retiring offsetting trades so gross notional falls and risk holds.
Multilateral
Offsets found across many firms at once, not pair by pair.
Initial margin
Collateral posted up front against what a position could lose.
CCP
A central counterparty between both sides of a cleared trade.
Cross-currency swap
Exchanging interest and principal in two currencies over time.
NDF
A currency forward settled as one net payment, usually in dollars.
MCP
Model Context Protocol, a standard way to plug tools into agents.
Human in the loop
A person approves an agent’s consequential step before it runs.
Evals
Repeatable tests that show whether an agent is ready to ship.
