I never did university, learned mostly off Codeacademy back in 2013. I never once listed this in my resume. I instead built website using the knowledge, contributed to open source, and then listed those things. Which seemed to work.

These days I don't do any personal projects or contribute to OSS, I just list my previous jobs and can ace any on the spot questions.

Expecting to be able to list the completion of an online course as an achievement is kind of silly. They are very easy to skim through without learning, and are only really useful for yourself to learn, not to prove anything.
