I don't get this. I have no education, no resume, no Linkedin and I've never applied for a job in my life. Employers/recruiters reach out to me, and I usually turn them down. I'm not humblebragging, I'm not better at my job than most people. What seemed to have worked for me was doing tons of FOSS work (unpaid, in my spare time). People started noticing me and it naturally picked up from there. I'd wager that actual, observable software engineering (FOSS) is simply a closer proxy for job performance than accreditation and past experience.
