    I am Java developer specializing in web projects and I have good experience with different Java frameworks and technologies including (but not limited to) most popular Spring and Hibernate. Also, I created AJAX front-ends based on jQuery, Bootstrap and DoJo on client side and various REST API frameworks on server side. Besides that I like developing and implementing non-trivial tasks that go beyond traditional CRUD action. Due to good knowledge of GNU/Linux OS (and its most popular daemons: Apache, Tomcat, MySQL/PostgresQL, Postfix/Exim, Named/Bind, iptables) I also can offer full support of application life from initial server setup to continued maintenance after main development is complete.  less
