Webdesign in React

I'm looking for a developer to improve (make them more beautiful) and expand some web pages written in React. There are 10 pages, some with text only and some with integrated functions such as a database and e-commerce. In general, it can be said that it is a new-generation job board with some new and innovative functions. Very interesting. I'm looking for a good professional who can finish the job by 1.12.2022, with a limited budget.
