    Ukraine - Last active: 07/30/2012 - Tests: 4 - Portfolio: 9

    4+ years xp in development of web-apps, complex sites and services that require scalability and conformation to the most current web standarts. You are welcome to use my strong skills in (D/X)HTML, CSS Layer 1-3, JavaScript/Ajax, XML/JSON, Python, Java EE with modern frameworks and different database engines such as MySQL, PostgreSQL, Oracle for developing featured web-2.0 websites as well as multitier enterprise-level web- applications. In my developing practice I use modern MVC/ORM/Ajax frameworks (such as jQuery, prototype-js, Spring, Struts, JSF, Hibernate, Tiles, etc. - take a look at the rest of my profile for details) in combination with strong OOP, design patterns, unittesting. That's why you'll get the product built using the best programming practices instead of "inventing the wheel". Over the last years I was working in relatively big outsourcing company. So it's usual for me to be envolved in a full development cycle of big web- applications, communicate with customers, have business trips to other countries and participate in remote teams.
