This guy...he's honestly the best programmer I've ever met, when I said what my project needed to be, he didn't even hesitate, not only that, but he went beyond my original idea and improved areas I didn't even consider when I told him what I needed, he responded every time, even super late at night, and honestly I can't praise him enough, if someone reads this, don't miss your chance to work with one of the best, honestly from now on whenever someone talks about how the internet gives us opportunities to meet amazing people, this is certainly the guy I'll be thinking about.
