Owning the company that is extending you the job offer you need for the visa is grounds for cancelling your visa—it's not guaranteed but if DHS find out in the future (like if you petition/apply for greencard) they'll bounce you.
Basically, do it if you're comfortable (maybe) being asked to leave the country on short notice.
You're right. Weekends project would be a better title.
We built an end to end proof of concept our first weekend on it, then spent another Sunday polishing it as well as a few hours here and there a couple of evenings.
I am sorry but what do you mean by modified email? I used sinatra(http://www.sinatrarb.com/) to build the web service and ruby for back-end. It is hosted on heroku. :)
Good job for the work. But seriously, I don't think you even have a MVP yet. If the purpose of this site is to correct people's accent, having a generate voice(huge electronic accent) is not acceptable at all.
You are right, robotic accents is not helpful (but hilarious though).
This app is mainly aimed at fixing the incorrect pronunciation of words, rather than the accent. If I ever get to add real human voices, then it will be even better.
