I have worked with Khaled during the development stages of the One Large Financial Application for Private Equity Client. It has been an absolute pleasure to work with Khaled as his professional approach and manner has been an assist to this development. Not once during the development did I feel unsatisfied with the service I received from Khaled, he is truly a great assist to his company. I look forward to working with Khaled again in further developments.

I'm very glad that you are my teacher. I'm not the best student, but you are the best teacher. Although we have only been together for three short weeks, I still feel that I have gained a lot. The good times passed quickly, and I was about to leave McGill and Montreal, the lovely and charming places. I used to think that the lessons in this project were not very practical, but in the process of learning, I found many operations are very useful. I really appreciate what you've taught me. And my university is in Ningbo, Zhejiang, China. If you come to China, you can call me by (+86)173xxxxxxxx. I'm always expecting you.

Mr Khaled, I really liked your course and your method. Frankly speaking, such course for the price we paid, is 1000 times nothing.

We took the Introductory Big Data training course from dataXper. Mr. Tannir has constantly provided us with great technological advice that takes into account our needs. Thanks to him, we have managed to learn and understand a lot of things in the world of Big Data. His strong skills in Big Data strategy will certainly lead to the development of a collaboration to help us prepare our action plan and our road-map to adopt Big Data technologies.
