Over two months, Jay-Ubisse enhanced the mini-plataforma-filmes-b4f repository by improving the film creation workflow, introducing client-side validation for required fields and a confirmation dialog to prevent accidental data loss. Using JavaScript and front-end development skills, Jay-Ubisse focused on user experience and data integrity, ensuring smoother and safer data entry. In the b4f-2-final-project repository, Jay-Ubisse delivered a Category Management API, adding routes and controller logic for product categories with Express.js and Mongoose, and addressed a user controller regression.
