Custom Apparel E-Commerce Website

I’m launching an online store that sells clothing people can personalise on-site. The core of the build is an e-commerce site with a seamless Shopping cart and a preset design gallery that lets shoppers pick a graphic, watch it appear on the garment in real time, then proceed straight to checkout. On my side, I need an admin area where I can upload new artwork, organise it into categories and attach it to different products without touching code. Customers should experience smooth browsing on mobile and desktop, clean product filtering, secure payments, automated confirmation emails and clear shipping options. You are free to work in the platform that suits you best—Shopify, WooCommerce, a headless React/Node stack or another solid solution—so long as I keep full control over products, orders and the gallery once the site is live. Deliverables • Deployed, fully responsive e-commerce website under my domain • Admin panel for product management and preset design gallery uploads • Front-end design preview linked to the Shopping cart and checkout • Brief hand-off guide or video showing me how to add future designs and garments I will provide hosting credentials, the initial product list and all artwork files. Please outline your proposed tech stack and estimated timeline when you respond.
