During October 2025, Diego developed a location input form, UbicacionForm, for the alquiler_front repository, focusing on frontend development with React, Next.js, and TypeScript. He implemented client-side validation to ensure that address fields were not left empty, providing real-time feedback to users and improving the quality of data submitted through the UI. The form featured basic CSS styling for a cohesive user experience and clear validation messaging. While the work was limited in scope to a single feature, it established a foundation for future backend integration and contributed to raising the front-end quality bar for location data handling.
