I’m building a university capstone and need a lightweight, fully custom e-commerce site that can showcase any type of product I decide to upload later (nothing is locked to electronics, fashion, or books). The brief is intentionally simple: the only core feature my instructors require is a working shopping cart with add-to-cart, update quantity, and checkout flow. No user accounts, product reviews, or off-the-shelf platforms such as Shopify or WooCommerce—this has to be coded from scratch so I can demonstrate my understanding of front-end and back-end fundamentals. A clean, responsive interface, concise codebase, and clear setup instructions are essential because I’ll need to walk through the project during my presentation. Language and stack are flexible (PHP + MySQL, Node.js, Python-Flask, or similar); just keep dependencies minimal and well-documented. Deliverables upon hand-over: • Source code with comments explaining key functions • SQL or migration file for the product and cart tables • Read-me guiding me through local setup and deployment • Brief notes on how to add more products later Once I can spin it up locally and successfully add items to the cart and proceed to a mock checkout, the project will be considered complete.
