DOS TWO followed Clarita, an Afro-Latina girl embracing her Puerto Rican roots while growing up in N.Y, inspired by our author's backgrounds. Together with a team of illustrators (Mara & Avery), animators (Helena) and coders (Juan), we aimed to turn the book into a fun, and educational resource for all Latino kids in the US.

Most kids' bilingual reading resources focus on grammar and vocabulary, but overlook storytelling and cultural identity — making language learning feel like a chore rather than a connection. For many Latin American kids in the U.S, this leaves them feeling disconnected from the language and unmotivated to use it.

User research also highlighted the value of gamification. Just like a teacher reviewing story vocabulary with students, I reimagined this interaction through playful games that connect English and Spanish text. From left to right, I explored a card-matching game where kids pair English and Spanish words, a word-builder game using terms from the manuscript, and a picture-to-word matching game.

From our interview with Professor Michelle Young Brown, we learned that understanding a child’s dominant language is key. If a child is stronger in English, it’s more effective to read the English text first, followed by the Spanish text. To support this, I included a language preference question in the onboarding flow.

In this project, I learnt:
Designing for kiddos!!!

Designing for kids has been incredibly fun. The UI needs to be easy to navigate and colorful, with clear interaction feedback to keep them engaged. It introduced me to a new user group I never expected to design for, and I loved the challenge.

Leading a x-functional team

Working with illustrators, animators, and programmers, I learned how to coordinate and amplify different strengths while defining the right product features and a shared design process that supported everyone.

Vibe coding

To make prototyping feel more realistic for testing, I used Cursor and Claude to code my designs. This made it much easier to gather meaningful feedback from kids and teachers since the experience felt close to the actual product.
