More about me

I'm a product manager who likes the messy early part — taking an ambiguous problem, finding the real user need underneath it, and shipping the thing that solves it. Over 4+ years I've delivered $520K+ in cost savings on a platform serving 80M+ people, launched a feature to 10K users, and picked up a Duke MEM along the way. Now I build AI products end to end — currently Tear, a multi‑agent research platform that cuts product research from 4 hours to about 10 minutes.

My approach

01

Discover

Every product starts with a gap: the space between what users say they want and what they actually need. I spend my time here first — talking to users, mapping how they actually work, and asking why until the real problem shows itself.

02

Define

Not every problem deserves a build. Before anything ships, I pressure-test it on four fronts — is it valuable, usable, feasible, and viable — then turn the strongest opportunity into a clear spec with success metrics attached.

03

Deliver

Ship small, ship often. I work in tight loops with engineering and design — prototype, test, refine — and for AI products, evals and guardrails are part of the build, not an afterthought.

04

Measure

Launch is the midpoint, not the finish. Every release gets a number attached — adoption, engagement, revenue — and the data decides what happens next.

Warner Bros. — Can they rewrite the script on entertainment?

ProblemDrowning in debt while its biggest franchises lose relevance and streaming rivals eat its lunch.

My callRevive iconic IPs with fan collaboration, unlock new revenue through gaming and VR, and use AI to cut production costs — while making Max streaming actually profitable.

So whatA clear path to position Warner Bros. as an entertainment ecosystem, not just a movie studio.

Tesla — Competitive strategy stress‑test

ProblemTesla's lead is eroding as legacy automakers and Chinese EV makers close the gap on price and range.

My callStress-tested its vertical-integration and supply-chain strategy against demand and pricing shocks — defend the moats worth the capital, open up the rest.

So whatA framework for deciding which advantages compound — and which quietly become liabilities.

Best kind of user research and A/B testing, on stage, you instantly find out which joke works and which doesn't.
