Based SF bay area

Meta WhatsApp Designed and shipped core messaging experiences for 3B+ users worldwide, incorporating AI-native workflows to accelerate team velocity.

Notification Strategy WhatsApp hadn't prioritized notifications in years. We had little data, little research, and no clear direction on where to invest. I partnered with cross-functional teams to build the strategy from the ground up, leading workshops, auditing the end-to-end notification experience, and running rapid experiments that uncovered what was actually broken. The work led to a north star direction for the notification ecosystem.

✨ AI native workflows

I built a custom generator to bypass backend dependencies and test different layout variants and states instantly. This significantly reduces prototyping time and allows the team to quickly align on the right user experience before engineers spend time building it.

Messaging experience I focused on the core messaging experience — everything from how you type a message to how you read one. I improved the composer, link previews, and @mention visibility in threads, and optimized group creation to drive a 3% increase in completion rate. *Further details are not disclosed due to NDA constraints.

Legalzoom Messaging Platform

LegalZoom connects small business owners with tax experts throughout the filing journey, But the communication between them was broken. Everything ran through email: customers didn't know who would respond, experts lacked context, and every handoff meant starting over. I designed the end-to-end messaging platform from both sides: a persistent conversation experience for customers and an integrated workspace for experts that surfaced everything in one place.

Evernote Task smart due date

Setting due dates is the primary way our users stay organized and engage with tasks, but clicking through traditional calendars creates a lot of unnecessary friction.    I led the end-to-end design of an intuitive input model that lets users simply type the way they naturally speak. The system works in the background to instantly recognize over 35 different date formats, turning text into task data. This made creating tasks with due dates faster and more seamless.
