Hello Haven · 2026

Analytics and referrals

Director of Growth Engineering

Growth only compounds when you can see what works. I built Haven's measurement from the first ad click through daily product use, then built a referral loop on top of it.

What I did

  • Built the full analytics stack, from marketing attribution to in-product usage analytics.
  • Built the referral program and the in-app UI that drives it.
  • Supported product testing and handled technical customer support.

Finale · Let's talk

Got something hard? Let's build it.

I want a long run on a product that's hard and matters, with people who've stayed up until 2 a.m. on something because they couldn't put it down.

Open to remote roles in AI engineering, product engineering, growth and GTM engineering, product management, strategy and special projects.
