    Java/C++/Perl professional

    Russia - Last active: 1 day ago - Tests: 11 - Portfolio: 1

    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.

For best results, please challenge me with something new to create from the ground up. I'm highly motivated by modern design.

Efficient modern software architecture is both elegant and practical: apps run faster.
