Global Personalized Canvas Gifting Platform

Built a full-stack global e-commerce platform from scratch for personalized canvas products — dynamic drag-and-drop canvas builder, multi-gateway payments across India/USA/Australia, and Shopify-level custom functionality.

Company Context

An e-commerce platform enabling customers across India, USA, and Australia to create and purchase personalized canvas products — custom photo prints, wall art, and gifting items. The product is the personalization itself: customers design their own canvas in real time before purchasing.

What Our Scale Partnership Revealed

The product required a real-time canvas builder where customers could drag, drop, resize, and position their own images on a canvas product with live preview rendering showing exactly what they'd receive. No off-the-shelf platform provided this.
Global operations across three countries meant three different payment ecosystems: Stripe for international/card, Paytm for India UPI and wallets, CC Avenue for Indian card processing. All three needed to work seamlessly in a single checkout flow.
International pricing, currency handling, and promotional mechanics needed to work across all three markets simultaneously.
SEO was critical — personalized product pages needed to be indexable and dynamically generated at scale for organic discovery.

Engineering Work

Built the full platform from scratch — custom architecture designed around the personalization-first product model.
Built the drag-and-drop canvas builder with real-time image rendering — customers see their exact product as they design it, with live preview updating on every interaction.
Integrated Stripe, Paytm, and CC Avenue as a unified payment layer — checkout intelligently routes to the appropriate gateway based on customer location and payment method.
Built dynamic pricing engine supporting per-product, per-region, and promotional pricing.
Implemented SEO infrastructure: dynamic page generation with structured metadata for organic indexing at scale.

System Outcome

Full personalized product creation workflow live — customers design and purchase custom canvas products in a single seamless flow.
Global payment infrastructure operational across India, USA, and Australia.
Dynamic pricing and promotional system supporting international commerce mechanics.

Engineering Breakdown+

Canvas Builder: Built on HTML5 Canvas API with a custom interaction layer handling object selection, drag positioning, resize handles, and z-order management. Image rendering is done client-side for speed, with a server-side rendering step at order confirmation to produce the print-ready file at the required DPI.

Payment Gateway Routing: Abstracted all three gateways behind a unified payment service interface. Gateway selection determined by a rules engine: customer country + selected payment method → gateway. Each gateway implementation handles its own authentication, webhook processing, and error normalisation.
