You want too see public projects on my github profile? I'll work on my public projects during office hours, deal? There are companies which become hysteric on the mere mentioning of the words "public", "open source", and "GPL" and doing it, while already employed, will undoubtedly initiate multiple meetings with a bunch of security and legal guys staring judgmentally at you. I hope such companies are more forgiving when candidate has no public github/gitlab/bitbucket.
