If you aren't getting to the first call there is something up with your resume. Are you applying directly or working with a recruiter? Applying directly is a roll of the dice in my experience. I have gotten just one job in tech by applying directly of the many I have had and it was a total surprise. For all others I have worked with a recruiter.

From a hiring manager perspective, I'm more interested in experience, level of ownership in past work, and good performance on technical screening questions. I rarely look at GitHub profiles and candidates rarely list them.

From my personal experience, what you have publicly available in your GitHub can only hurt you unless you are the owner of a successful open source project. As you said, you have a lot of half-baked stuff. It's probably not worth making public.

Will the lack of online presence be an issue? Maybe or maybe not. Some people seem to care a lot about whether or not someone has a LinkedIn and whether or not they keep their job history up to date. I do not personally care, but I will say LinkedIn is a low effort investment of your time. As much as I don't care for it, I have landed multiple jobs thanks to having a reasonably up to date profile that recruiters look for.
