    Senior Java/PHP developer

    Belarus - Last active: 1 day ago - Tests: 4 - Portfolio: 6

    Hello. I have worked for many companies to make new sites and products in last eight years. I worked in teams of over ten people, know all tricks of this work, but working in small teams is a little easier. I have experience in the following areas and technologies: Java - 8 years Java 1.8 - 1 year JSF 1.2 - 8 years JSF 2.x - 3 years PrimeFaces - 2 years MyFaces - 8 years RichFaces - 1 year Apache Tomahawk - 8 years Spring framework - 8 years Hibernate ORM - 4 years Hibernate ehcache, envers - 1 year iBatis ORM - 8 years maven - 5 years Tomcat 6-7 - 8 years Tomcat 8 - 1 year SVN - 8 years git - 1 year IntelliJidea - 8 years The most important thing is the structure of the project, modularity. The project should be clear for any developer who will work with it after me. So I start with maven, then add spring, hibernate, and then everything depending on project specification. I always use TO layer so structure is domain-dao-services(TO)-server. I am have a big experience in refactoring, moving projects under maven and latest versions of framework, for example JSF 1.1->jsf 2 (2.2). I would be happy to work on amazing java project. I am also a PHP Codeigniter developer so I would be happy work on an interesting PHP project. So please, if you need an experienced java or php developer, I may be a good fit, it would be great experience for both of us. Looking forward to cooperation. Thank you in advance Regards, Aleh
