Worked on the LuccaSA/lucca-front repository, focusing on targeted improvements to front-end user experience and reliability. Developed a new prop-driven configuration for the phone number input component, introducing the noAutoPlaceholder option to give developers explicit control over placeholder behavior while maintaining backward compatibility. Addressed a reliability issue in the Number Format Directive by ensuring the onTouched callback is consistently triggered on blur, even when input values remain unchanged, thereby improving form interaction state and accessibility. All changes were implemented using Angular, HTML, and TypeScript, with careful attention to minimal surface area and clear commit traceability throughout the process.
