CHECKMATE

AI powered shopping app

AI powered shopping app

I designed the Checkmate app, an AI powered savings platform that generates offers like discount codes and cashback.


My work covered growth, from onboarding new shoppers to the engagement loops that brought them back, built on cashback boosts and notifications. I also owned the core experience, which meant surfacing offers where and when they were useful.


I used Claude Code to iterate, prototype and open PRs against the codebase so the work got implemented.


Case study coming soon…

TINDER

Monetization on Tinder

As lead designer on Tinder's Revenue team, I owned design strategy and execution across premium features, paywalls, checkout, and monetization experiments. The first thing I noticed when I got there was how inconsistent it all was. Every upsell looked like it came from a different app.

I treated it as one system instead of a pile of one-offs, redesigning the paywalls and upsell moments and adding new places to sell that still felt like Tinder rather than an interruption. This led to stat significant results and a revenue high for Tinder.

Community & In-App Events

Community & In-App Events

In 2020 everything shut down, and the reason most people opened Grindr, chatting with someone they might actually meet, went away with it. We needed new reasons to come to the app that had nothing to do with chat.


We started with live virtual events, first a Charli XCX DJ set, then more live streams through the spring, building up to Pride Perseveres, a month of nightly events with Q&As, performances and merch drops. Each one had to be findable, so I designed dedicated placements on the home grid with a countdown to the next event. Once enough of this content was running, I designed the Community tab as a permanent home for it, alongside Grindr's editorial and health resources.

CHECKMATE

Checkmate for Brands

Checkmate partnered with brands to deliver exclusive offers, generating incremental revenue for each partner.


I built Mate, a self-serve platform where brand teams track their revenue impact, launch and adjust campaigns, manage creative assets, and act on recommendations for which segments to target next.

My Tags

My Tags

I noticed people were already putting hashtags in their bios as a way to say who they were. Nobody had asked them to, and the app did nothing with it, so those signals just sat there instead of helping anyone find each other.


That became My Tags, a way to find people who share your interests. I ran user testing and worked with LGBTQ+ organizations and trust and safety, so the tags would work for everyone. Adoption came fast, as many instantly added tags to their profile.

Just for You

Just for You

Women kept running into low-quality profiles on Tinder. No photos, short bios, no verification. It made the app feel like work, and engagement and retention dropped.


I led design and user research on Just for You, a feed of curated profiles. Research came first, figuring out what women actually counted as a good profile, and that set what we filtered for. We used machine learning to build the picks, and I designed the feed so it read as a short list worth looking at instead of an endless stack.
