Natly

In active development

A bilingual civic-education platform helping Spanish-speaking immigrants prepare for the U.S. naturalization process with quizzes, flashcards, study tools, and interview simulations.

The challenge

Make citizenship preparation clearer, more accessible, and less intimidating in both English and Spanish.

My contribution

Product strategy, application architecture, UI/UX, and end-to-end full-stack development.

Planned AI experience

Natly will adapt preparation to each learner’s profile. Learners with limited English will receive guided practice for understanding questions and responding confidently to a USCIS interviewing officer. The platform will also provide alerts about relevant citizenship news and changes to naturalization rules.
