Description
WordPress Product Catalog Plugin Developed a fully featured WordPress plugin designed for automated product catalog management with Excel import, custom post types, taxonomies, and an optimized frontend display. The project was commissioned by an internal client seeking a scalable, maintainable, and high‑performance solution to handle large product datasets in a fluid and secure environment. Key Contributions: Modular OOP Architecture: Built a PHP modular architecture inspired by PSR‑4 standards, organized into five main classes handling admin logic, data synchronization, frontend rendering, and debugging, ensuring clarity and maintainability through automatic autoloading. Excel Import System: Integrated PhpSpreadsheet via Composer to automate large‑scale product imports from Excel (.xlsx/.xls), including dynamic column mapping, batch processing, real‑time progress updates using WordPress Transients API, and AJAX‑based UI refresh. Custom Post Types and Taxonomies: Created a WordPress data model using one custom post type ("product") and four taxonomies (category, type, color, collection) with full metadata management (SKU, weight, stock), REST API support, and relational consistency. Admin Interface Design: Developed a complete back‑office experience integrating Bootstrap 5 with WordPress native styles, including custom meta boxes, real‑time notifications, event logs, and data management tools for maintenance and error tracking. Frontend with AJAX Filtering: Implemented dynamic shortcodes ([catalog_products], [catalog_search], etc.) and custom templates enabling AJAX filtering by attributes (weight, color, stock, type), pagination without reload, and user‑friendly navigation. Modern JavaScript Architecture: Used ES6 modules and the Module pattern to structure UI components, with smooth CSS3 transitions, loading states, and state‑based interaction for responsive and performant frontend behavior. Security and Best Practices: Implemented nonce checks, data sanitization, and capability control for user actions, ensuring compliance with WordPress security standards and plugin development guidelines. Performance Optimization: Designed a multi‑layer caching strategy with Transients API, SQL query optimization, and detailed logs with timestamps to monitor import performance and minimize database load. Project Delivery: Completed within three weeks through structured development phases including architecture design, functional core development, and interface integration, resulting in a robust enterprise‑grade catalog solution ready for real‑world use.
