1. Project Task
Develop a comprehensive Full-Stack "turnkey" solution for an online custom clothing store (t-shirts). The main goal is to fully automate the customer journey: from selecting the cut and color to creating an individual print in the interactive designer, instant online payment, and managing this order by the site administrator through a secure backend.
2. Implemented Technical Functionality (Full-Stack Architecture)
+ Client Side (Frontend & E-commerce)
Catalog and Categorization: Distribution of products by cut categories (Oversize, Regular, Premium, etc.) with an interactive size chart and color selection.
Seamless integration with the Designer (Core Feature): When selecting the color and size of the t-shirt in the catalog and proceeding to customization, the system automatically transfers the selected parameters to the designer. The customer does not need to set everything up again.
Interactive 2D Designer:
Uploading user’s own images (PNG/JPEG).
Adjusting print size and positioning using precise sliders (range sliders).
Drag-and-Drop Canvas API: The ability to freely drag and scale images with a mouse or touch events on mobile devices directly on the t-shirt layout.
Smart Dynamic Cart: Full management of items in the cart (adding, changing quantity, deleting) with seamless return to previous steps without losing selected order configurations.
Secure Review System: Only authorized users who have actually purchased the product can leave a review on a specific item (purchase status verification in the database is implemented to protect against spam and manipulation).
+ Transaction Module (Fintech)
Acquiring Integration: Form for collecting contact details and delivery information.
Instant Payment: Full integration of contactless payments through Apple Pay and Google Pay for maximum conversion to purchase directly from mobile devices.
+ Backend and Administrative Panel (Management & Security)
Admin Panel: A separate secure interface for tracking and processing orders. Allows viewing current orders, details of selected custom layouts, changing processing statuses, and editing items.
Security and Brute-Force Protection:
Access to the admin panel is protected by a login, password, and unique URL route.
Protection against password guessing: After several failed authorization attempts, the user's device is blocked at the hardware/session level.
Super Unlock Code: Access after blocking is possible only with a special long decryption key (backup code), ensuring 100% protection against unauthorized access.
3. Project Technology Stack
Frontend: React.js / JavaScript (ES6+), HTML5 Canvas API, Tailwind CSS, Drag-and-Drop API, React State Management.
Backend: Node.js, REST API, JWT authorization.
Services: Integration of payment systems (Apple/Google Pay acquiring), Vercel/Render for optimized deployment.
4. Business Value of the Solution
The development is fully ready for scaling for real business in micro and macro merchandise production. It eliminates the need to maintain designers for layout approvals, as the customer independently creates the finished product, pays for it in 2 seconds via Apple/Google Pay, and the administrator immediately sees the ready specification for printing in the admin panel.
