Lami Kabir
March 2019
He was able to debug really fast. Saves you a lot of time and money. He is very kind and caring and enjoys what he does. He is not in it for money. He loves helping people and you can see that from him. You will know what I mean when you have a session with him. I feel bad for all the people missing out on this great opportunity. In my opinion he is the best mentor i had so far. I would not be writing so kindly about him if I was lying.
