Opencart Website Modification journal3

I am looking for a skilled developer who can make modifications to my Opencart website using the journal3 theme. I need both design and functionality changes to enhance the user experience. Although I have a rough idea of what I want, I don't have specific examples to provide. I am open to suggestions from the developer.

Skills and Experience:
- Proficiency in Opencart and journal3 theme customization
- Strong understanding of user experience best practices
- Ability to make design changes that improve visual aesthetics
- Experience in implementing functionality changes to enhance website performance
