Hii,
I've good knowledge of Web based and Desktop based application development and have worked in previous various web projects. Apart from that, I've experience in C#.Net Core 2.2,3.1, Asp.net, PHP, HTML, Javascript, SQL Server, Web API, Web-Services and Web API Integration.
I'm sure we can help you with your requirements.
Please allow me to have a close discussion over a chat so that can get your points exactly and then only after getting 100% understanding over the project scope will let you know the revised cost and time frame.
Regards,
Ravi
