He don't know anything about the work i am asking, but he told that he know it. He didn't finish my task, moreover, he is asking me to pay money. i don't recommend him.

Not advisable , he did not know how to resolve the issue

Venkat Sudhakar understood the work and completed on-time. Overall, working with him was good experience.

Did not know how to visualize data. Unreasonable and demanding payment for delivering project milestones. If you want to work with someone that demands payment before delivering, feel free to choose Venkat Sudhakar G.
