Fresh Modern E-commerce Site Redesign

My current e-commerce site converts well but looks stuck in another decade. I want the entire visual layer and front-end structure rebuilt so it feels fresh, modern, and inviting the moment visitors land. The redesign should embrace contemporary colour combinations, clean typography, generous white space, and fluid responsiveness across desktop, tablet, and mobile.

Core priorities
• A streamlined layout that highlights products first and shortens the path to checkout.
• A robust product search and filter component (think live search, category filters, price sliders) implemented in a way that stays lightning fast as the catalogue grows.
• Pixel-perfect consistency: every new screen, modal, and micro-interaction should share the same design language.
• Code that slots neatly into my existing back-end without breaking current payment and inventory logic.

I’m open to your preferred stack—whether you work in React, Vue, Tailwind, Bootstrap, or pure HTML5/CSS3—so long as the final deliverables are easy for my developer to plug in. Design mock-ups can be provided in Figma, Adobe XD, or Sketch; a clickable prototype that demonstrates key flows (home, category, product detail, cart) will secure quick approval.

Acceptance criteria
1. High-fidelity mock-ups for all core pages and states.
2. Fully responsive front-end code, W3C-validated and cross-browser tested.
3. Integrated product search & filter working end-to-end on a staging URL.
4. Handover package with assets, style guide, and concise setup notes.

Timeline and milestone suggestions are welcome. If you’ve delivered bold, future-proof e-commerce fronts before, I’m keen to see how you’d re-energise mine.
