High-End UX/UI Design for Professional Venture Capital Brand

I am looking for a top-tier designer who specializes in professional UX/UI design to elevate my brand, Ascendia Ventures.
We already have a strong brand identity (logo attached), which features a gold and navy blue palette, symbolising growth, infinity, and security. We now need a designer who can translate this premium feel into a world-class user experience.
The ideal freelancer will:
Have a proven track record in high-end, corporate, or financial UX design.
Understand how to balance a "luxury/professional" aesthetic with clean, modern usability.
Create wireframes and high-fidelity prototypes that align with our brand's gold/navy theme.
Focus on a seamless, intuitive journey for our clients.
If you have a portfolio that showcases sophisticated and functional design, I would love to see your work. Please include examples of similar projects in your proposal.
