Hello, I have read your project details carefully and would like to discuss my skills and plans with you. I am an c# expert and have been developing and experimenting with it for 7 years. Great things come from passion and that's what I have for c# development. My motto is simply "quality and time". Nowadays there are many developers that rush projects and put delivery time above quality of the project. I on the other hand like to finish projects in a timely fashion that fits the project owner's needs but also work extremely carefully to ensure quality is met. Hopefully, you will consider hiring me as I'd love to start a chat to further discuss the proejct. Hoping to talk soon, cheers!

Hello, Please clarify: - if you want to make external access possible or just from inside the server local network, - if the server in on-premises or it's a cloud server, - in case it's on-premises, then what is your Internet connection router vendor\model, - in case it's cloud, then where it is hosted and what's your tariff plan.
