Snap Discover & Stories

Head of Discover and Stories Engineering · October 2016 – February 2021

San Francisco Bay Area

Context

Led the engineering organization behind Snapchat Discover & Stories during the platform's hyper-growth years, covering recommendation systems, creator and media workflows, story infrastructure, moderation systems, and content distribution for hundreds of millions of users.

What I built and led

  • Built Snapchat's Discover personalization platform from the ground up and scaled personalized content systems from early product vision to 200M+ daily viewers
  • Managed and scaled an 80+ person engineering org spanning backend infrastructure, ML/ranking, Android, iOS, and web engineering
  • Partnered with product and leadership teams on recommendation systems, creator ecosystems, content quality, reliability, experimentation, and large-scale mobile infrastructure

What was technically hard

  • Building a recommendation system that served hundreds of millions of users across wildly different content types (publisher stories, user stories, shows, editorial) with real-time personalization
  • Scaling the engineering org from a small team to 80+ while maintaining quality and shipping velocity through Snapchat's most volatile growth period
  • Balancing content quality and moderation at scale with the speed required by a social platform where content is ephemeral

What I learned

  • How large-scale consumer recommendation systems actually work in production, not just in papers
  • How to build and scale an engineering organization under hypergrowth pressure
  • How content ecosystems, creator incentives, and platform dynamics shape technical decisions
  • How to operate under constant market shifts while maintaining long-term technical bets

Why it matters now

The Snap chapter is where I learned to operate at scale. Recommendation systems, content platforms, and personalization at 200M+ daily viewers gave me intuition for how AI-native products need to work in the real world. That experience directly informs how I help founders think about product-quality loops, ranking systems, and scaling engineering teams.
