What should be an open-source project, so as not to scare the employer?

Question

ASP.NET

There is a potential employer on the one hand, and me on the other. There is a solid experience in the desktop in C #, but not enough experience in the Web.
I really want to get a job asp.net mvc developer. I know - javascript, jquery, html, css, asp.net mvc(web api), GoF, TDD.
So. What should be my own project on github so as not to scare away the employer who finds out that I only worked on the desktop at my main job?
ps. It is desirable that this project could be implemented in a month, no longer ... but there was a prospect for expanding the functionality.

Answer 1

Say that you specialized more in backend. I am a web developer, but I am far from a guru in layout, and although I know about javascrtip, I had to get acquainted with special nuances already when I was doing a single page application.
Nobody needs projects on github, except for nerds-stratapers. Not a single serious developer who has tight deadlines and a lot of tasks will spend time after work on all sorts of githubs, open sources and other crap. There (on pet projects and pure open source) either start-ups sit to promote the project / team, or consultants who are paid for a very specific area in the same Linux, or evangelists who are punished for chatting.
I don't have a single project that I could show to the client without violating the NDA.

Answer 2

For your task, the project must be in a private repository so that a potential employer does not see it.
It is very difficult to understand another area in a month, but you can get the initial skills. Just don't show it to anyone: the first pancake is always lumpy.
