LEAD PRODUCT MANAGER · NEW YORK

I build AI agents and financial systems that turn high-stakes workflows into scalable products.

Production AI, 0→1 financial infrastructure, and measurable operating leverage — built for workflows where speed matters and trust matters more.

01 / FEATURED WORK

Three ways I ship.

Production agents, AI product judgment, and financial infrastructure. Start with the flagship stories; the deeper systems track record sits underneath.

INDEPENDENT BUILD / AGENTFIT

Which workflow should become an agent?

Move the inputs. AgentFit turns workflow characteristics into an illustrative fit score, autonomy recommendation, control pattern, and capacity estimate.

FINANCIAL INFRASTRUCTURE TRACK RECORD

Four additional 0→1 / production systems across optimization, validation, FX, and margin.

Employer work is intentionally generalized. Internal implementation details, client information, and sensitive system specifics are omitted; visible product names are contextual only.

02 / HOW I BUILD

Agents should earn autonomy.

My default is not “put an LLM in the loop.” It is: understand the workflow, expose the right tools, bound the action space, evaluate behavior, and prove economic value.

Reusable MCP servers, domain APIs, Pydantic-typed actions, deterministic services, human approval, and evaluation / QA baselines.

01

Start with the workflow

Map the hidden handoffs, constraints, exceptions, and failure costs before choosing the model.

02

Design the control plane

Separate model judgment from deterministic logic and make consequential actions observable and reviewable.

03

Measure the operating model

Track whether the product returns capacity, improves adoption, changes unit economics, or creates revenue.

04 / ABOUT

Technical enough to go deep.
Product-minded enough to know why.

I build AI agents and financial infrastructure for complex, high-stakes workflows.

Lead PM at Quantile (LSEG), shipping production AI agents and 0→1 financial products. My work has cut expert workflows from hours to minutes, scaled operations without added headcount, and generated $3M+ in new and expansion ARR.

Previously built pre-trade margin and derivatives analytics at OpenGamma.

Building something technically hard
that should feel simple?

If you’re building AI-native products, financial infrastructure, or software that turns complicated enterprise workflows into something dramatically better, I’d love to talk.
