Senior Product Manager Los Angeles, CA · Available

Most trust failures are infrastructure failures. A decade building risk, fraud, and Trust & Safety platforms taught me exactly where they hide.

I'm a product manager specializing in the infrastructure behind risk, fraud, and Trust & Safety operations. Seven years at Amazon shipping signal architecture, automation, and platform work that served 10M customers, 2M businesses, and 100M+ annual transactions. Today I'm in pre-launch with my first founder venture, JoinPlay, and building agentic AI tools for PMs.

01 / Selected work

Three projects where AI does real work. Not demos. Not decoration.

Every piece of work below has AI doing real work: in the product, in how it was built, or both.

JoinPlay

Every activity shows two scores: one for the sport, one for the people.

The rec-sports world optimizes logistics and abandons belonging. JoinPlay is a consumer platform pioneering a new category — social sports integration — built for what incumbents ignore. Sole PM & builder: dual-fit matching system, JTBD research across 13 competitors, architecture, and MVP. Tightening core loops before public launch.

Spec-Check

Stress-test a PRD before a single line of code.

An AI review system that runs your product spec past five specialist agents — technical feasibility, metric clarity, stakeholder alignment, edge-case coverage, and data privacy — and returns a readiness score with actionable gaps.

02 / Professional journey

A decade in the operational seams — risk, fraud, Trust & Safety, and the platforms that hold them together.

    Building a consumer platform pioneering a new category — social sports integration — that matches users to rec-sports communities on skill and social fit.

    • Mapped 16 JTBD across three tiers, rated 13 competitor platforms, and identified the unserved Tier-2 social integration gap.
    • Designed a dual-score matching system (Activity Fit + Social Fit) across skill, availability, location, and group culture.
    • Authored product strategy, system architecture, PRD, metric tree, GTM plan, and safety framework end-to-end.
    • Shipping MVP solo with an agentic stack; public launch follows mid-size-city beachhead strategy.

03 / How I work with AI

I run a one-person product org on an agentic stack, handling discovery, architecture, build, and launch without a pod.

Generative and agentic AI are load-bearing in my workflow, not decorative.

A.

Agent-assisted discovery

I run structured JTBD interviews, then use LLMs as synthesis partners to cluster quotes, find the disagreements no one named out loud, and draft problem framings I can pressure-test against the transcript.

PRD red-teaming

Every spec I write goes through Spec-Check — my own agentic review system — before stakeholders see it. Five specialist agents catch gaps I'd otherwise ship.

Vibe-coded prototyping

I prototype entire flows end-to-end — not Figma, but working HTML, real state, real APIs — so I can user-test and iterate in hours instead of sprints.

Signal & metric design

For risk & T&S work I still reason about signals by hand, but use agents to generate test cases, stress distributions, and edge-case catalogs that would take days to assemble manually.
