Yellow Circle and Gray Letter U

Create a logo featuring a bright yellow circle with a sleek, modern gray letter 'U' at its center. The design should incorporate keywords provided by the user, ensuring they are integrated seamlessly into the logo. Use elegant fonts that convey professionalism and creativity, while maintaining a unique and technological feel. The color combination should be visually impactful, with the yellow circle symbolizing energy and optimism, and the gray letter 'U' representing stability and sophistication. Aim for a modern aesthetic that stands out and captures attention.
