I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
Wait, I have a bit of a sticky with "If all you have is Open Source as something you can show an employer".
Open source is all you can show an employer. Everything else is hearsay. You can say, "I worked on the doohickey that tamped down vibrations in the flux capacitor" if you want, but unless you have permission to show your work, it's just words. Sure, you can back it up in an interview, but you can do the same if it was open source.
Having open source software you can show people is always of benefit to the company looking to recruit you. Of course, if it's crap then you're not going to get far, but...
For further actions, you may consider blocking this person and/or reporting abuse
