web application changes, on .net , c#, mvc

I'm looking for an experienced programmer to assist with making changes to an existing web application. I need guidance on what changes should be made, but I have all the necessary resources available and a rough timeline estimate. I want someone who can quickly understand the existing codebase, analyze how it works, and identify and implement the necessary changes. This is a full-stack project, using .NET, C#, and MVC. If you have the skills and strong communication abilities to help me make my application exactly what I need, please reach out. Thanks!
