Featured Work
Facebook Story Midcards: An Easier Way to Share
+17.4% improvement to publish rate by adopting my design standards
Problem: People want to share Facebook Stories, but they aren’t sure what to share.
Solution: Smart, ready-to-share suggestions from the user’s photos.
Challenge: With a vast scope, extreme timelines, and almost no testing, the team had to be scrappy and creative to make the project work.
What I did: I created content for dozens of variants and was hands on with every aspect of their design. I also co-created the design standards that continue to define them today.
Outcome: Today, roughly ~1 in 10 stories shared on Facebook come from these sharing suggestions.
Facebook Story Tray Tiles: Doing more with less
+6.38% improvement to publish rates by adopting my content approach
Problem: Sharing suggestions are popular, but can be easy to miss.
Solution: Add sharing suggestion entry points to the story tray at the top of Facebook’s home page.
Challenge: Story tiles are extremely limited in space, and have to work across several languages and situations.
What I did: I tried several content approaches, each more successful than the last. By the end, I was shipping and testing my own experiments.
Outcome: These tiles are now one of the primary entry points for sharing suggestions.
Oculus Horizon Worlds (2021): A Social-First Achievement System
Launched in 2021 with 300K+ users in the beta release alone
Problem: We needed an achievement system, but it couldn’t intimidate new users.
Solution: Badges that were meaningful to those who earned them, without turning them into a status symbol that might make new conversations intimidating.
Challenge: Horizon is a game, social experience, and building tool, all in one. It needed an achievement system that could cover everything.
What I did: I created the entire system and named all the individual achievements.
Outcome: My achievement system was included at launch.
Automatic AI Captions on Photos
Launched in 2026 across Facebook Stories and Posts, with no reports of offensive outputs.
Problem: Photos with captions perform better, but many users don’t bother to write them.
Solution: Using AI, we could to analyze photos and generate safe, shareable caption ideas.
Challenge: It’s incredibly hard to predict what a user would write, and even if we could do it perfectly, it can come off as creepy.
What I did: I wrote the AI prompt that generated captions, focusing on short, safe, reliable captions that sounded like what you’d see on a post card, not what the user themselves might write.
Outcome: AI captions has launched across multiple surfaces and formats. My focus on short captions was validated by data that showed our best performing captions were just 15 characters.
Malwarebytes for Windows (2019): Refreshing a Fan Favorite
Launched a complete redesign of the company’s flagship product
For more than a year, I worked as the sole content designer on a complete redesign of Malwarebytes for Windows, the company’s flagship product. As a core member of the design team, I worked on the product from early planning meetings through to its general release. I wrote nearly all the UI copy, as well as most of the marketing copy for its launch.
Malwarebytes for iOS (2019): Blocking Spam Made Easy
Launched a brand new iOS app, rated 4.6/5 on the App Store
As the UX writer on Malwarebytes for iOS, I collaborated with engineers, UI designers, and product experts to create copy for every screen in the app. From button text and feature names to instructions and disclaimers, I tried my best to make every aspect of the app usable, uncomplicated, and user-focused.
