I already have an online store dedicated to nail polishes and related care products (on shopify) but have been very unhappy due to multiple issues, and I need a developer who can take the project from concept to a live, fully functional e-commerce website on another platform. The one non-negotiable feature is a smooth shopping-cart and checkout workflow that makes it effortless for customers to add multiple shades, topcoats, and accessories to their order and complete payment without friction. Everything else—design language, mobile or tablet optimizations—can follow your expert recommendation as long as the final site looks professional, loads quickly, and can grow with my product catalogue. If you have experience building beauty or fashion-focused online shops, even better—please tell me about it. I’ll supply product photos, descriptions, and branding assets once we get started; you’ll handle structure, theme setup or custom coding, payment gateway integration, basic inventory configuration, and a quick walkthrough so I can manage listings on my own after launch. Let me know how you would approach the build and roughly how long it would take to deliver a polished, ready-to-sell storefront.
