App Code Customization

I'm looking for a developer to customize a ready-made app source code. The primary focus will be on UI/UX design changes.

Customizations needed:
- UI/UX design changes
- Home screen, Navigation menu, Profile page, and all other screens

I have some design references, but I need a skilled developer who can interpret and implement them effectively.

Ideal Skills and Experience:
- Experience with app development and customization
- Strong UI/UX design skills
- Ability to work with design references and implement changes accordingly
- Familiarity with [specific technology or programming language used in the source code] is a plus

Please provide examples of previous similar work.
