Shopify Store Redesign & Customization (Modern Multi-Category Store)

I’m looking for an experienced Shopify designer/developer to redesign and customize my existing store ZIGZAG ZONE, which is already live but currently looks basic. The goal is to transform it into a modern, premium and conversion-focused multi-category ecommerce website selling electronics, smart gadgets, kitchen products, fashion, beauty, mobile accessories and other trending items for an India-based Gen-Z and young working audience, with strong mobile-first design. The work includes creating a high-converting homepage with hero banner, category sections, trending products, fashion highlight, trust section, promotional banners, testimonials, newsletter and professional footer; clean collection pages with filters and sorting; and a conversion-optimized product page with sticky add-to-cart, trust badges, delivery info, reviews and related products. Smooth micro-animations, full responsiveness and speed/performance optimization are required so the final store feels like a professional brand and is ready for paid ads and scaling traffic.
