Hello there,
Greeting of the day!
As a devops/linux evangelist, I have 11+ years of rich experience in devops/Linux/networking and automation domains.
I have worked on all the major devops technologies and have designed, implemented and supported complex use-cases Please feel free to check my profile for more details.
Regarding your requirement, I must say it's a good idea but don't really rely on .NET for it. There are better technologies available out there already. Having worked/currently working on a similar portal requirement, I see a lot of layers to the project(which you might already have thought about).
I would like to know more about the requirement. Let's connect in PMB to know more and then finalize the price and timelines details. Please check my profile for more information.
