Hypothesis
As the Senior Growth Product Designer at Mondly, I led an ambitious project to redesign the trial experience for one of the fastest-growing language learning apps with over 125 million users.
If we streamline navigation, enhance accessibility, and declutter information during onboarding, learners will progress more smoothly to their first session and feel more capable from the outset.

“This feels way smoother. I actually wanted to finish it this time.” — Anderson
This project reminded me that clarity beats cleverness — when users understand what’s next, they commit faster. Simplifying interaction flow isn’t just good UX, it’s good growth.
