Mobile developers: what's your biggest struggle in presenting work that you've done?

I know most of you have your own side projects/businesses but perhaps some of you are looking for a job or trying to showcase your work to recruiters but you don't know the best way to do it because writing and design aren't your core skills.

What's the biggest roadblock?

What's lacking in profile builders now?

What's something you struggle with most in trying to showcase your work?

Thanks lovely people.
