The Calm App in a Noisy Market • Koto
new language is rewarding. But choosing where to start is overwhelming.
Too many apps, too much content, too little clarity.
Vocabulary is the foundation. Yet no one wants to spend more than 30 minutes a day on it.

Every Unanswered Review Is a Missed Opportunity • Adeona
Restaurant owners are too busy to manage reviews, yet a single unaddressed or generic response costs customers. This project explores how an AI co-pilot can automate review management—generating authentic, on-brand responses in seconds to turn a neglected task into a real driver of customer retention.

Live, but driving users away • Kumori
Two years ago I shipped Kumori as a developer — no design background, no user research. Just code. The numbers were brutal: 8 monthly visits and a 1-minute average session.
I came back as a product designer. Same product, different lens. Target: triple session time and increase monthly visits to 20.

About me
Hey, I’m Pierrick Bernard, a Product/UX Designer with 2 years of experience.
I started learning UX Design from a PDF a friend sent me, and I immediately got hooked. I devoured every resource I could find on the subject. What I enjoy most is finding market opportunities to address user needs while keeping business goals in mind.
I’ve always been passionate about design in all its forms, from graphic design to furniture and beyond. I’m also inspired by art and architecture, which feed my designer’s eye and inspire me to find new solutions.
