You know what,
Hello! My name is John Kern. The Best Software Engineer, Web Site and Web App Designer, Developer and Full Stack Software Engineer and Architect from Netherlands.
I stopped reading here. I mean how much one can praise himself? I mean if you were that good, wouldn't big names like Facebook, Google hire you instantly? There is a shortage of good developers in the world anyway. I'd love to see your GitHub

That is because I dont want to be hired. I want to work for myself. I dont have a github account actually, I dont own an opensource project, but I know how to use and tweak them to get the job done.
If you have real projects that you think will fit my expertise, just tell me then I will show you what I am capable of

If someone hires you to build any web app, then whether you work for yourself or for someone else?
why don't you create a web app for yourself and make money with them? Then you will work only for you, no need to have Github account, you won't have a boss over your head.
Off course, no one will hire you if you can't show your skills on previous work.
good luck with your programming.
