Shopify Store Redesign and Optimization

I run Femtoarts.in, a D2C lifestyle brand selling premium posters, tumblers, copper bottles, and more. The site is currently built on a basic free Shopify theme.
I’m looking for a Shopify expert/freelancer to:

✅ Audit the current store (UX, functionality, SEO)
✅ Suggest and implement a complete design upgrade
✅ Add high-converting features (filters, reviews, personalization, popups, etc.)
✅ Ensure mobile-first performance and fast load speeds
✅ Optimize the store for SEO and conversions
✅ Complete all work within 10 days

What I Need From You:
Portfolio of 3–5 Shopify stores you’ve worked on
Your approach in a few bullet points
Estimated quote & turnaround time
Any theme/app recommendations (paid or free)
Looking to start immediately.
Drop your proposals or DM me with your portfolio!
