Otavio Filho enhanced the Enfermagem course enrollment form in the teamAreadev/Salaberga repository by streamlining the user interface and improving database reliability. He removed explicit modal labels, instead using placeholders and disabled inputs to provide context, and converted the PCD field from a select to a checkbox, which simplified data entry and reduced errors. On the backend, Otavio addressed inconsistent database connectivity by reverting a problematic DSN and standardizing the database name, ensuring stable connections across environments. His work demonstrated proficiency in front-end development, UI/UX, and database configuration using HTML, CSS, and PHP, with clear documentation and traceable commits.
