    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.

    Senior Java/J2EE developer, Software architect, 9+ yrs of experience

    Czech Republic - Last active: 04/09/2013 - Tests: 8 - Portfolio: 2

    Developer of Java based applications (J2SE & J2EE) My long-term goal is to specialize on tools for development and architecture of Information Systems - like IS for hospitals, offices, company intranets and such. Over the past years I've worked on such systems. I really don't like creating simple web presentations, without any business logic inside. I prefer creating such product, where you can actually TALK with your customer and stay in contact. I believe that great products can be created only through tight cooperation with customer - through an agile, iterative development. Specialties J2SE, J2EE 5 (not so good in previous versions; preferring JBoss over other application servers), many Java frameworks (like log4j, hibernate, TestNG, Jasperreports, Spring and others), SQL (Oracle mostly), OSGi. Gained solid experience with Eclipse RCP. I touched (tried) things like Grails, Spring MVC, jQuery and many others, but I don't have rock solid experience in these...
