Onboarding Overhaul

Result: 16% increase in account creation

When I joined Vocalbeats, the team was small, and product leads didn’t consider email sign-up a priority. However, I discovered a growing trend in East Asian and European markets—many users were hesitant to provide their phone numbers.

To validate this insight, I conducted further research and, after gathering significant supporting data, was assigned to a small team to implement an email login flow.

Over a month, I:

Created journey maps, wireframes, visual designs, and prototypes.

Conducted multiple rounds of user testing to refine the design.

Collaborated with the development team to ensure a smooth launch.

As hypothesized, the introduction of email login contributed to Buz’s new user base growth in the following months.

Buz Unfiltered

Result: Buz reached 1 million users by having users invite their friends to Buz Unfiltered

I was the sprint master and lead designer for Buz Unfiltered, a holiday event that drove up user engagement and resulted in Buz reaching 1 million users.

Users would then receive a link to Buz, prompting them to download the app and create an account to access the full message.
