The project centres on creating a PHP-driven e-commerce site whose first release focuses exclusively on a rich, searchable product catalog. Core requirements are: • Product catalog: unlimited items, multiple images, SEO-friendly URLs and automatic breadcrumbs. • Advanced filtering options: users must be able to narrow results by category, price range and at least three custom attributes (e.g., colour, size, brand). Filtering needs to work instantly without full page reloads (Ajax preferred). Although checkout and payment processing are not in scope right now, the codebase should be structured so those modules can be dropped in later without refactoring. An admin dashboard is part of the deliverable and must allow CRUD operations on products, categories and attributes through a clean UI. Preferred stack: modern PHP (8.x) with either Laravel or a lightweight framework such as CodeIgniter; vanilla PHP is acceptable if MVC is respected. Front-end should be responsive (Bootstrap or Tailwind) and pass basic Lighthouse audits. Acceptance criteria 1. Catalog pages load in <2 s on a typical shared host. 2. Filters update results instantly and without page refresh. 3. Admin panel actions persist to the database and reflect immediately on the front end. 4. Source code is well commented, version-controlled (Git) and delivered with a short README for setup. Please include a brief outline of your proposed architecture and any similar catalog work you have completed when you submit a bid.
