I am a backend developer first and foremost, I don't have a portfolio and even if I did I wouldn't know what to put in it because my work experience is closed source/private or APIs, and the things I could actually put there are hobby game projects that might make me seem unprofessional or completely unrelated to what I am currently applying to.
Of course I always link to my GitHub when prompted, but more of the same applies to that as well.
If there are any backend devs here, what do you do in this situation?
