    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.

    E-learning perfectly combines my artistic/ creative design talent with my passion for training, development, and education. Having worked with both Instructor Led Training and Computer Based Training in my past management experiences, it is a pleasure to be on the development/ design end of production. I feel it is imperative to tap into the knowledge of what drives motivating, successful education in training across industries. The trick is presenting it in a way that is interesting to the presentee and in turn effective in training. I earned my Psychology degree from The University of California, San Diego with an emphasis on Development & Education, and a minor in Visual Arts. I consider myself fortunate to have continued to develop both areas of my passion: working with people and the arts. I have spent over 10 years in staff development, building effective and efficient teams through my roles in management. While putting a special focus on driving individual strengths and positive working environments.
