Enterprise Product · Berkeley, CA

I lead enterprise products at scale — and still build by hand.

Director of Product Management at Workday, where I own a nine-figure-ARR product line serving more than a thousand enterprise customers — full stack, from C-suite strategy to engineering spec. I haven't put the tools down: I built tapsa.ai solo on the Claude API, and I co-taught an AI-native PM cohort to students across several universities.

Proof, not adjectives

01

Built tapsa.ai solo

An AI knowledge-graph product I built end to end on my own — Claude API, Cursor, Vercel. No team, no co-founder: just me shipping it and debugging the real post-launch failures on nights and weekends. It's live.

02

Lead a nine-figure enterprise product line

As Director of Product Management I own one of Workday's workforce planning product lines — nine figures in ARR, more than a thousand enterprise customers, and a team of senior and staff PMs. I operate the full stack: strategy with the C-suite, spec with engineering.

03

Co-taught an AI-native PM cohort

Designed and ran a four-week AI-native PM cohort alongside a university faculty member — teaching students from UC Berkeley, UC Davis, and Northwestern to get genuinely hands-on with AI tools, not just theorize about them.

04

Advise ololand.ai

Enterprise AI product and go-to-market input for an early-stage team.
