    Once one person told me "If you do something, always do it with the highest quality" this person is "Vincent Hardy" 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 was participated in different conferences like speaker: "JEEConf" (one of the biggest conference in Ukraine) with speech "Hadoop, NoSql, RDBMS, Katta" "DevTime" with speech "Hadoop in practice" "Pacemaker" with speech "Hadoop, Distributed Computing" I'vE done review of the book "Hadoop in Practice" it took about one year. 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. NoSql (Hbase, MongoDB): for storage and processing unstructured data.
