Hello Haven · 2026

Haven Vision

Built end to end as Director of Growth Engineering

Haven is a voice-first AI assistant for everyday life. Vision gives it eyes: point your camera at something and Haven sees it in real time, talks it through with you, and uses what it already remembers about you to help.

What I did

  • Built the real-time pipeline that streams the user's camera to the AI during a live voice conversation.
  • Connected Vision to the agent's memory so answers reflect each user's history and preferences.
  • Designed the in-app experience for starting, running and ending a Vision session.

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.
