    Once one person told me "If you do something, always do it with the highest quality" this person is "Vincent Hardy" www.w3.org/People/VHardy/. And I took this rule for my work. How does it works: communicating with the customer I always try to understand his problem, his pain. I try to establish communication and believe that this is one of the most important task for success. Always do a careful analysis of the requirements. If there is no requirements (this is usual situation), I try to help you to clarify situation, to give some advice, to find the best way for your business. Always try to provide a quality service at all stages of cooperation.

I helped to review and test source code inside the book and I did review for all chapters of the book. I was trying to help authors to achieve best result in writing this book. And think it was successful. Experience: I have experience in different areas from writing desktop applications to large servers apps. Right now my specialization is Big Data and everything related to this. Mainly: Hadoop (Pig, Hive): For storage and processing big amount of data.
