Adrian K.

Java Programmer - J2EE, SpringMVC, Wicket, Hibernate, jQuery, Android


Bielsko Biała, Poland


Over 10 years of experience in IT, concentrated on Java technology, especially on Web technologies and frameworks. My favorites are lightweight technologies and frameworks like Spring, Wicket, Lucene Search/Solr and Hibernate, but I have experience with more sophisticated ones like ESB (Progress Sonic), CouchDB, bayesian networks. My area of expertise are also Javascript and jQuery/Ajax all for Web 2.0 approach, my CSS/HTML knowledge allows me to make ready to use projects just from the graphics artist design, for responsive layouts I prefer Twitter Bootstrap. I know mainstream social solutions like Facebook API, Twitter API, authentication with them or Google SSO. I ... morealso write applications for Android platform, and have a good knowledge of C++, and Windows API. I can do simple Ubuntu Linux/FreeBSD administrative tasks for deploying applications on server. I have very good knowledge of PHP5 and SQL. I used to work with MySQL, PostgreSQL, H2 and HSQL databases. In Java development I usually use Hibernate with its criteria API, with occasional SQL performance optimization. In my job I usually use Maven2, as the greatest build and dependency helper, of course I know how to use Git or Subversion, how to resolve conflicts, merge branches, make tags, I know a lot on unit testing (JUnit, Mockito, etc.), and continuos development - I worked with Hudson, Sonar, TeamCity. My code is clean, good naming conventions, for both Spring and Hibernate I use annotations, with small amount of XML where needed. I'm able to work in different timezones and I keep the deadlines even the shortest ones. I want to work on web projects: web pages, REST/SOAP APIs, high availability applications servers, Android applications and backends for them. less
