UI/UX improvements for web app

I am looking to make significant improvements to the UI/UX of my web app, focusing on enhancing the visual design. Currently, feedback from users is mixed. The user base of my web app is quite small, less than 100 users. I am searching for someone with the experience and skill to help me in this endeavor - making the user interface more visually appealing and user-friendly. With the right person, I am confident that the UI/UX of my web app can be greatly improved upon. If you think you are the right person for the job, get in touch.
