Shopify Theme Customization Expert Needed

I'm looking for a seasoned Shopify theme editor to help customize my purchased theme for my business website. The theme is already installed on my Shopify store, but it needs to be tailored to match my brand’s aesthetics and functional needs.

Customisation Needs:
- Adjusting the color scheme and fonts to align with my brand
- Modifying the layout and structure for optimal usability and visual appeal

Content Creation:
- I'll handle content creation myself, so no assistance is needed here.

Functionality Enhancements:
- Implementing product filters and sorting options to improve user experience

Ideal Skills:
- Proficient in Shopify theme editing
- Strong understanding of UX/UI design principles
- Excellent attention to detail

Experience:
- Prior experience customising Shopify themes
- Portfolio of work with similar projects

I'll provide links to theme examples that I like for reference.
