Forget improving your CV. Make sure it's good enough. Depending solely on your CV makes you average. Are you average? Of course not, you're on HN! Build practical shit. No seriously man, making your own language will invoke a yawn as another commenter said. Build a web app, build a piece of software that has practicality. Build anything, as long as it can be demoed.

I realize that you want a new job now. Well, that's going to take patience. Don't spam your resume! Trust me, I use to interview and this was very common... you could detect these types.

Start today. Just build something that can be demoed, something preferably practical.

Good luck man!
