Shopify theme customization it for our brand

I am looking for a Shopify expert to customize my current theme to suit my brand's modern and professional aesthetic. The ideal candidate will have experience in improving existing features and functionality on Shopify stores. The project will involve making changes to the layout and design of the site while maintaining a minimalist and clean look. The primary color scheme for the brand will also need to be incorporated into the design. The candidate should have a strong understanding of Shopify's platform and be familiar with coding languages such as CSS and HTML.
