Hi!
I'm experienced developer and I have worked on the silimar projects. I've worked with government institutions, banks, bureaus, private schools and many other types of businesses. My primary skills are C# and VB.NET when it comes to building CMS applications like the one you require. I don't have many in the showcase because they are strictly confidential and I had NDAs, but there are some examples I can show you.
Feel free to message me!
Best regards,
Marko
