Jan Gorecki developed and enhanced core features for the shopsys/shopsys repository over 15 months, focusing on backend architecture, security, and admin tooling. He engineered robust access control systems using PHP and Symfony, implementing both RBAC and ABAC models to strengthen route protection and permission management. Jan refactored CRUD operations and datagrid components for maintainability, introduced automated code standards enforcement, and optimized image delivery and caching for performance. His work included modernizing CSRF protection with PHP 8 attributes, improving localization, and upgrading CI/CD pipelines with Kubernetes. These contributions resulted in a more secure, scalable, and developer-friendly platform.
