I don't know what the state is now, but when I was still in the working world, linkedin was the place to leave your resume and look for contacts. I can see that mentioning repositories of projects of yours on your resume can bring some interest to the technical staff, but in bigger companies or when recruiting agencies are used it probably won't make much of a difference. Human resources department is the first hurdle to take. And what do they look at? Education and work experience, meaning actual paid jobs done.
It is getting through the door that is of the issue, and for that you have to have a good and impressive resume with short and to the point information. I don't think having a lot of internet presence will help here, unless it is of such weight that you don't need a job anymore. Like Dave Jones for instance.
.... Call them. Then call them again. Then drive there and keep knocking on their door and asking for the boss. ...
And pestering someone by showing up unannounced and keep on doing that, despite being told not to, is called harassment and is also illegal. And if I ran a company and someone did that repeatedly, I would call the cops on them.
But for someone who wrote that he is sitting on his ass, leaching of society, because live spit him out, it is a lot of words without real action. Instead of trying to convince us of how intelligent you are, go out and get an actual job. Try your mentioned technique and see how far it gets you.
