To be honest I looked at github - there's barely any activity, projects have little if any descriptions, the professional experience has been 12 years of mix of project management and customer support, some 2 years of freelance and contract devops work. Medium posts are mostly crypto related. Now compare that with LinkedIn about section, and there's an entirely different picture.

It could be that the reason you are getting the interviews is the Linkedin profile (especially as often companies encourage interviewing people with atypical background), but maybe you fall short of the image you are projecting? The form of the interviews might not help highlight your skills, of course, but it's probably not the only factor.
