Dear employer,
I am a Senior Software Engineer and I worked a lot with C# .NET, with extensive cloud experience. I have VS 2019 installed, and I can use .NET Core 3 or .NET Framework if you prefer - I recommend CORE to be honest. I have my own Azure dev account, so I am fine with using my own stuff during development. I will finish in 4-5 days and I am happy to document my work.
We can discuss more in private.
Best regards,
Istvan
