Backend Development with Symfony Framework: I leveraged the Symfony framework, which powers PrestaShop's backend, to build a robust and scalable system. By using Symfony's modular structure, I was able to develop custom modules, integrate third-party services, and optimize the platform for performance. The use of Symfony ensured that the platform could handle increased traffic and complex operations as the business scaled. My work focused on enhancing database management, optimizing product catalogs, and improving overall backend performance.
