I need a browser-based product customizer built with Fabric.js—or another modern HTML5 canvas library if you have a strong preference—that slots smoothly into an existing website. The tool must let shoppers add text overlays, upload their own images, change colours on designated zones, and work with predefined templates so they can start from a “ready-made” layout instead of a blank canvas. I’ll supply the product mock-ups (PNG/SVG) and template artwork; you handle the front-end logic, the canvas interactions, and a lightweight configuration panel so I can add new items later without touching code. The finished design has to export as high-resolution PNG or SVG with transparent background so it’s print-ready. Key deliverables • Responsive, embeddable customizer module for the web • Support for text overlay, image upload, colour change and templates exactly as listed above • Admin JSON or simple dashboard to manage products, colour layers and pricing rules • Clean, well-commented code plus a brief setup guide so my dev team can drop it into our site Everything should work in the latest Chrome, Firefox, Safari and Edge. If you’ve built similar tools, a quick demo link will move your proposal to the top of the pile.
