Lucas focused on enhancing the professional account workflow in the LucasOtw/SAE3_ScoobyTeam repository by developing a targeted UI feature that introduced API Key integration into the account modification form. Using PHP and front end development skills, Lucas added a dedicated API Key input field, a city input, and a submission button, while refining UI text for improved clarity. The work involved backend and form integration within consulter_compte_pro.php, laying the groundwork for API-driven account management and smoother user interactions. Over the month, Lucas concentrated on feature delivery and user experience improvements, demonstrating depth in web development and C programming without addressing bug fixes.
