I used Mubashir again based on his past Gigs with me, and he continues to provide a good service. Needs to work on his checking procedures for data entry however, since I had to correct his drafts at least three times before he got it right.

This about the third time I've used Mubashir for Data Entry and am quite happy with his work. He is communicative and responsive, and always asks before making assumptions. He also keeps to the required timelines.
