Worst ever dumbo... Go to him if you have ample time to complete the job or dont worry about its completion.
I haven't seen any one who is so irresponsible. He never kept the time line he committed. On top of it, his mobile is always switched off. He will switch on only when he feel like. At his office in Tippasandra, his employes are also clue less about the status of the activity. They cant reach Mr Ravi either. His employees said, "His mobile is the only way to reach him. Most of the time it is switched off. He will only call us when needed"
I had to literally yell at the employees couple of time to warrant a call from Ravi.
Better stay away from him.
