The most important and the most mastered by me are JAVA (and around frameworks) and databases (complex DML and DDL queries, SQL scripts). I have worked with huge amounts of data, that is why I have learned how to optimize application and tune db. My objective is to go deeper into subjects I have already known, to become a technical expert. http://www.wymiengierke.pl
