Frontend Developer for Kids' App

Project Overview: We are looking for a skilled frontend developer to build a lightweight, highly visual web application designed for in-store touch tablets/kiosks. The sole purpose of the app is to let children create their own seamless, tileable patterns using our pre-made Creative Library of images. The project needs to be fully completed, tested, and deployed within 2 months. Target Audience & Environment: Users: Children (needs a simple, large, intuitive UI with no complex menus). Hardware: In-store tablets/short kiosks (touchscreen-first interface, locked in landscape orientation). Key Features Required: The Art Board (Canvas): A central canvas area where users can build their design. Creative Library Sidebar: A scrollable drawer containing our pre-made PNG elements. Users drag-and-drop or tap an element to place it on the canvas. Canvas Interactions: Kids can tap an item on the canvas to move it, scale it (pinch/handles), rotate it, or delete it (trash bin icon). Real-Time "Tile" Preview: A small side-window or toggle feature that instantly shows how their current canvas looks when tiled seamlessly across a large surface. Save/Print Functionality: A simple "Done" button that flattens the pattern, generates a high-resolution seamless repeating pattern image (JPEG/PDF optimised for Postcard or Gift Wrap dimensions), and saves it to a local folder or sends it to a local network print queue. No user login or account creation required. Tech Preferences: HTML5 / CSS3 / JavaScript Canvas framework like Fabric.js, Konva.js, or p5.js to handle the heavy lifting of image manipulation. The app should be built as a Progressive Web App (PWA) or a localized web app so it can run fullscreen offline/locally on a kiosk browser. What We Provide: All PNG assets for the Creative Library. Final print size dimensions and technical specs. To Apply, Please Share: Examples of any interactive canvas, drag-and-drop, or pattern/photo-editing web apps you have built. Which JavaScript framework/canvas library you would recommend for this 2-month timeline and why.
