Technical Evaluation Framework: Vetting PrestaShop Developers

PrestaShop is a modular, open-source eCommerce platform with an enormous footprint across Europe and Latin America. In modern releases (PrestaShop 8+), the core architecture has transitioned to the Symfony framework, requiring developers with modern PHP engineering standards.

1. Modern Architecture: PrestaShop 8 & Symfony Standards

• ▸
  Symfony Integration: Modern PrestaShop development relies on Symfony routing, dependency injection, and Twig templating for administration. Vetted developers adhere to Symfony best practices rather than legacy procedural PHP scripts.
• ▸
  Clean Module Development: All custom business logic must be packaged into isolated modules utilizing PrestaShop's hook architecture. Ensure the agency submits code compliant with official PrestaShop coding and security standards.

2. Database Tuning & Caching Infrastructure

• ▸
  High-traffic PrestaShop stores require dedicated server configurations. Inquire about the agency's setup for OPcache, Redis/Memcached, and web server optimization (Nginx with FastCGI caching).
• ▸
  Ask how they handle database query bottlenecks on large stores with complex combinations (product attributes, sizes, colors) and multi-currency exchange feeds.

3. Red Flags in PrestaShop Agency Procurement

• ▸
  Abusing the /override/ Directory: Heavy class overrides in the /override/ folder create catastrophic conflicts when multiple modules attempt to override the same core method. Modern developers use hooks and Symfony services.
• ▸
  Unverified Marketplace Addons: Installing dozens of unvetted third-party addons that inject render-blocking JavaScript or create memory leaks.
• ▸
  Ignoring Staging & Deployment Pipelines: Deploying module code directly to live production servers via cPanel or FTP without automated testing.
