NORTHFORM — Functional E-commerce Store Concept

A self-initiated functional e-commerce concept built to demonstrate a complete browser-based shopping flow. NORTHFORM is not a client project or live store. All brand, product, price and order data are fictional.

What this proof demonstrates

• 10-product catalog with categories, search and sorting
• product variants with visible colour changes, size validation and persistence
• local cart with quantity updates and removal
• three-step checkout with standard, express and pickup delivery
• test payment success and decline paths
• clear form validation, payment errors and order-confirmation states
• responsive desktop/mobile behaviour verified across 13 scenarios

The user-facing catalogue, cart and checkout are functional in the browser. Payment processing, server-side orders, inventory, shipping, tax, email/SMS and courier connections are simulated and would be integrated for a production build.
