Continue Existing DIAMOND_TS WinForms Automation Project

This project is a continuation of my existing DIAMOND_TS software developed in C# WinForms. The software and source code already exist. I need an experienced .NET developer to continue working on the existing codebase without changing the current project structure... (Budget: ₹600 - ₹1500 INR, Jobs: .NET, .NET Core, ASP.NET, ASP.NET MVC, C# Programming, Git, IIS, Microsoft SQL Server, MVC, Selenium Webdriver)
