Modern Nutrition E-commerce Website for Shopify

I need a full-featured online store for a sports-nutrition brand, visually and functionally on par with https://www.sprintfit.co.nz/. The site must feel clean and modern, load fast on mobile, and make it effortless for visitors to discover products, read peer feedback, and check out in a few clicks. Core requirements • E-commerce structure with category and product pages that mirror the clarity of SprintFit • Robust product search plus layered filters (flavour, goal, brand, price, etc.) • Built-in user review system so shoppers can rate and comment • Secure payment gateway integration (credit/debit cards and common digital wallets) Design A modern aesthetic—ample white space, strong imagery, crisp typography, subtle animation—while keeping the purchase flow intuitive. I will supply logos, colour palette, and product photos; suggestions on additional visual direction are welcome. Platform & tech I’m open on stack choice—Shopify, WooCommerce, or a custom framework—as long as it supports the features above, scales easily, and allows straightforward content edits. Deliverables 1. Fully responsive website deployed to my domain and hosting 2. Admin dashboard configured for inventory, orders, reviews, and promos 3. Payment gateway tested in live mode 4. Basic SEO setup (metadata, clean URLs, sitemap) 5. Brief hand-over guide or Loom walkthrough covering daily operations Acceptance criteria • All listed features work on the latest versions of Chrome, Safari, Firefox, and Edge, desktop and mobile • Load time under 3 seconds on GTmetrix for the home page • Checkout process completes without errors using at least one live transaction Please outline your proposed platform, timeline, and any similar builds you’ve launched so I can gauge fit and move forward quickly.
