Back to original languageAbout Walid
Certified Acquia Senior Drupal Developer and Technical Lead, with over 7 years of experience in Drupal 8 to 11, PHP 8, and Symfony.
I design, develop, and maintain complex Drupal platforms: custom modules, APIs (REST, JSON:API), migrations, Search API / Solr, Drupal Commerce, performance, and security. I also handle architecture, scoping, workload estimation, code reviews, and team leadership (up to 4 developers).
I work on high-stakes projects for clients like RATP, BNP Paribas (Arval), AMF, the Légion d'honneur, and BRGM — both through service companies and directly.
My working method: clean and tested code (PHPUnit, PHPStan, PHPCS), reliable deliveries via CI/CD (GitLab, Docker, Platform.sh), and constant attention to accessibility (RGAA) and security. I also use AI assistants (Claude, GitHub Copilot, ChatGPT) judiciously to increase velocity without compromising quality.
Available in Île-de-France and remotely (full remote possible), for Drupal / PHP-Symfony missions: development, version upgrades, existing system takeover, API design, or technical lead role.
