How I help

  1. Conversion & monetization

    Funnels, landing pages, pricing, checkout, and experiments that turn more intent into revenue.

  2. Onboarding & activation

    First-run experiences, time-to-value, and lifecycle flows that help users reach the good part faster.

  3. Engagement & retention

    Churn diagnosis, habit loops, reactivation, and product changes that give people a reason to return.

  4. Product & growth strategy

    Positioning, prioritization, measurement, and launch support — with enough execution to make the plan real.

About

I studied psychology at NYU, so I start with behavior and intent before features. Most product problems are really attention, motivation, or friction problems wearing a costume. I care about UX and the small stuff, and I’d rather build a rough version than write the perfect doc about it.

Years ago I tried to build an app called Pearup in college. It never launched, but it’s what made me want to get good at this.
