I design the moments where people connect.

Currently building social experiences at Snapchat with Cursor and Claude.

Previously led the swipe stack and introduced dynamic profiles at Tinder.

Designing with AI as a daily tool. This portfolio is one output: my design, built with Claude. Poke around.

Social Games

Games on Snapchat were camera filters with no product investment behind them.

I saw the opportunity in the data, commissioned a research study, and shipped three bets tied to what we learned: a games drawer inside chat, fullscreen lens UX, and a turn-based flow that made playing with friends legible.

All three landed. I got CEO buy-in to go big on Games and earned a dedicated squad.

We scaled it into a proper product area with 30M daily users in less than a year.

  • 30M Games DAU
  • ↑ 2.9M Snaps sent
  • ↑ 120% Game Video Posts on iOS

Topic Chats

Topic Chats was a half-finished public-chat MVP. The surface worked, the product didn't. Most chats opened with a wave of 'hi' posts and went quiet, because the topics were too broad and never enough people were in chat at once.

I reshaped it into a live-events product anchored in sports and fandom. I designed the growth loops and high-leverage features (like the live scoreboard), and shaped the roadmap sequencing that got us to scale.

  • ↑ 71K Incremental U.S. DAU
  • 40K Peak concurrent users in chat
  • 208K Messages sent per week

Dynamic Profiles

Tinder profiles were fixed: same content order for everyone, nothing personalized.

Teams wanted to test layouts, but experiments collided and UI drifted without a shared system.

I led a six-month, four-milestone build of Tappy Cloud and TaCo, turning the profile into a backend-driven surface where teams could quickly configure, test, and integrate with ML and AI models for more personalized profiles.

  • ↑ 20% Likes sent across all experiments
  • $50–110M Attributed revenue lift
  • 100+ Tappy experiments launched with TaCo

App Redesign

Tinder's design language and profile system had barely changed since the app's inception. Profiles felt shallow because the content was shallow, and the app felt outdated because we hadn't invested in refreshed visuals or new interactions in years.

I designed Sparks: Prompts, Quizzes, and refreshed swipe and match animations that gave people more to react to. Started as a 2022 Hackathon win, shipped globally in 2023.

  • ↑ 0.8% Subscription Cash
  • ↑ 0.3% Days Active
  • ↑ 0.9% Likes Sent

Festival Mode

When IRL events came roaring back post-pandemic, Tinder had no real way for festivalgoers to find each other or plan their season together.

I designed Festival Mode 0→1 on Tinder Explore: a season-long social discovery experience around live events and music, grounded in the festivalgoer persona. Shipped in time for the start of music festival season.

  • Likes sent and convos started vs. main stack
  • ↑ 10% Tile opens on Explore
  • 2 months From kickoff to launch
