I have been working for 100's projects in past 3+ years related to Designing, Web Designing, Mobile app Designing for the clients spread all over the world. I provide my work always in time and even before the timeline and I can bet on this :)
After work completion I always provide clients with maintenance too (if required). I work mostly as per US timezone to work one to one with clients, so timezone if never a barrier for me. I am known to Wordpress, so I provide Designing with Integration of it as well.
