I wish he would apply for a job with us. I don't see any contact details, otherwise I would ask him directly.

I was thinking the same thing. Best I could find was the developer email listed for his calculator app: https://play.google.com/store/apps/details?id=com.projectfan...

[Edit] Which makes me realize that the submitter for the original was him: https://news.ycombinator.com/user?id=pr_fancycorn - so that may lead to some way to contact him.

Ah, thank you!
