Modern Mobile-Friendly E-Commerce Site

I’m building a new online store that will sell physical products and I want every part of the shopping journey to feel effortless on desktop and mobile alike. The overall look should stay modern and minimalistic, so clean lines, plenty of white space, and a focus on product imagery are key.

Core functionality I need you to deliver includes:
• A robust product catalogue with categories, search, and advanced filtering so shoppers can quickly narrow by size, color, price, etc.
• Detailed product pages that support multiple images, pricing, offers, and—crucially—customer reviews and ratings alongside related-product suggestions to encourage upsells.
• A smooth cart and wishlist flow tied into Razorpay for payments and eKart for delivery and real-time order tracking.
• Secure registration / login for customers plus an intuitive admin panel where I can manage inventory, customers, and orders without touching code.
• WhatsApp chat embedded for instant support, SEO-friendly structure, speed optimisation, and the usual security and QA checks before going live.

I’m open to the stack you’re most comfortable with—whether that’s a popular e-commerce framework, a headless setup, or a custom build—as long as it stays lightweight, scalable, and easy for me to update. If you’ve got ideas for additional third-party API integrations that can boost conversions or automate fulfilment, let’s discuss them.

Once finished, hand-over should include all source files, documentation for routine tasks (adding products, updating banners, processing refunds), and a short walkthrough so I can hit the ground running.

If this sounds like a project you can knock out of the park, tell me how you’d approach it, which tech stack you recommend, and a rough timeline from kickoff to launch.
