Job Description
Project Context
We operate a WordPress/WooCommerce e-commerce website specializing in decorative tiles and ceramics. Currently, our product customization configurator relies on pre-generated images (192 color variants per pattern), which creates:
An explosion in the number of assets to store and maintain
High loading times
Rigidity in catalog evolution
Significant administrative complexity
We want to replace this system with a dynamic configurator based on HTML5 Canvas, enabling real-time color customization of each sub-pattern composing a tile, without image multiplication.
Mission Objective
Develop and integrate a WooCommerce product configurator that enables:
Real-time color customization of each tile sub-pattern
A realistic visual rendering as a tiled wall (repeated mosaic)
A responsive interface (desktop, tablet, mobile)
Simplified admin management of products and their configurations
Technical Specifications
Product Data Model
Each product (tile) consists of multiple layered graphic sub-patterns:
Tile background
Decorative elements (squares, circles, triangles, petals, etc.)
Variable number depending on the product
Each sub-pattern:
Is represented by 1 single transparent PNG image (512x512px)
Has its own customizable color palette
Expected Visual Rendering
The configurator must display:
A mosaic preview simulating a tiled wall
Each tile measures 20x20cm in reality, but display size is adaptive (e.g., 60px desktop, 45px tablet, 30px mobile)
Sub-patterns (motifs) are repeated as patterns via HTML5 Canvas
Each sub-pattern can be independently colorized in real-time
Rendering must remain smooth and performant
Required Features
User side (front-end):
Color selection interface per sub-pattern (clickable color swatches)
Real-time preview of final rendering
Full responsive design
Add to cart with saved chosen configuration
Administration side (back-end):
Interface to easily create/edit configurable products
Sub-pattern management: image upload, stacking order, names
Color palette management per sub-pattern
Rendering parameter configuration (tile sizes by screen)
Ideally via Custom Fields (ACF) or native WooCommerce interface
WooCommerce Integration:
Storage of customized configuration in cart
Display of configuration in order and invoice
Expected Deliverables
Custom WordPress plugin or child theme with:
Reusable configurator module
Admin interface for managing configurable products
Modular JavaScript code:
Generic Canvas rendering engine
Responsive management
User interaction handling
Performance optimizations (lazy loading, cache, debouncing)
Documentation:
Admin user guide
Technical code documentation
Deployment guide
Training on configurator management (1-2h video call)
Technical Constraints
