    Poland - Last active: 10/23/2011 - Tests: 2 - Portfolio: 4

    I took up with programming about 18 years ago, then it was only my hobby, but about 9 years ago my passion became also my work. My professional experience begins with web development. I started with Perl, PHP which I eventually left for Java based technologies. During my carrier I gain not only high skill programming experience but also code maintenance and refactoring skills. Continuous integration, build systems like jenkins and bamboo, test driven development are engineering tools used by me in every day work. I am mainly concerned on software engineering, but I have had a role as a team leader and analytic as well, what helps me in understanding not only the code but also business word. I am highly competent and I care about being up on new trends and technologies in software engineering. I continually extend my knowledge.
