 * Moderniser le frontend : seconder le développeur Front pour migrer la stack legacy (RequireJS/Bower, Bootstrap 2/3) vers un environnement moderne (Bun, Webpack Encore, Stimulus).

Stack technique :

 * Backend : PHP 8.1, Symfony 6.4 (évolution vers Symfony 7), Doctrine (base de +120 entités)
 * API : architectures API, idéalement API Platform 3
 * Tests : PHPUnit, culture du test automatisé
 * Frontend : Webpack Encore, Bun, Stimulus (migration depuis RequireJS/Bower, Bootstrap 2/3)
 * Outils IA : usage d'outils augmentés (Cursor, Claude) pour accélérer le delivery
