The site is LAMP(php) stack on AWS ec2 and jquery on the front-end.
Let's see, roadblocks:
- front-end -- getting everything to work tolerably in IE7+
- front-end -- the bookmarklet. Definitely the bookmarklet. Huge issues injecting javascript into DOMs. The version live now finally works every time without fail. (details: array leaks, style conflicts, calling in jquery, etc)
- back-end -- nothing too serious. Joins in mySQL took a while to get right. Ajax can be finicky but nothing too bad.
- Server -- we hadn't set up DDOS protection on our amazon server and so the site went down a few times. There are some great tutorials for getting a Lamp stack up on ec2 - if you know what you are doing should only take five minutes.
Needless to say figuring out what to search is the biggest problem. Once you know what to search, stackoverflow and google can fix all your problems.
You should be fine, as long you are not using their property (hardware, software, phone etc) to work on your project. Also it should not be in competition with your company. Just to be on the safe side, you might want to tell your HR and see if they have any objections.
I worked with some really good .NET MVC developers on my last personal project. They worked USA Pacific time zone (9 to 5) and were available via skype and google chat. Let me know if you need their profile and I can shoot it to you in email.
If you are ok with Union City then I can connect you with someone who offers very cheap office space. Its a commercial building which houses insurance agents and stuff.
