During my internship at Numbered, I worked as a UX/UI Designer on improving the Coterie e-commerce and subscription experience. My focus was on key user journeys such as onboarding, the diaper size quiz, subscription setup and account management. The platform serves first-time parents, a target group that often experiences uncertainty when making product decisions. This made clarity and trust essential, especially in moments where users had to commit to a subscription rather than a one-time purchase. One of the main challenges was simplifying complex flows without oversimplifying the product. Subscriptions, delivery intervals and sizing logic introduce friction when presented all at once. Through UX research and flow analysis, I identified where users hesitated and where information caused confusion rather than reassurance. Based on these insights, I designed user flows and wireframes for multiple key pages. The experience was structured to guide users step by step, using progressive disclosure to reveal information only when it became relevant. This approach helped reduce cognitive load while keeping the experience aligned with Coterie’s premium positioning. Throughout the process, I iterated on designs based on feedback from the design team and the client. Particular attention was given to the quiz experience and subscription flows, ensuring they felt supportive rather than overwhelming, and intuitive rather than transactional. The final outcome supports a smoother onboarding and subscription experience. By combining clear structure, calm visual hierarchy and trust-building elements, the platform helps parents make confident decisions with less friction while maintaining a premium brand feel.
