I work during normal business hours from 10:00 AM IST to 7:00 PM IST. However, if there is a need, I can work extended hours to meet the deadline or attend the meeting.
I prefer to have some idea of what's to be worked on, but a full written scope isn't needed. a phone/Skype call might be helpful. I may have questions along the way, so, one person should be in my contact.
(This is important to keep a fast pace)
