Worked with Chirag on a Freelance job and was very happy with the results. He delivered on time and was available afterwards for questions. He can be a little difficult to 'find' in that you sometimes see he's online but doesn't respond right away to your message. However, within a couple hours he does respond so once I figured out how he worked I adjusted to suit. That's my only 'complaint' which isn't really a complaint once you understand that about him. I would definitely work with him again in the future if the need arises. 100% satisfied.
