    Software Engineer over here! Domain-driven design enthusiast with passion for structuring flexible OO design with PHP. Certified as UML Professional (Fundamentals) by Object Management Group on December 2013. For the last 4 years I've been actively developing web applications using Zend Framework (since July 2012 I'm Zend Framework Certified Engineer). Expert in design patterns with over 4 years of professional experience. I'm developing enterprise web applications, file sharing systems, websites, web application frameworks, etc. Achieving high quality of code, good performance and reusable object-oriented software design is my primary goal when working. I don't underestimate documentation as my source code is always well documented, with end-user manuals when needed. In the last two years I've gained rich experience with Dependency Injection and Service Locators and successfully applied those approaches my projects. I'm always ready to learn new approaches, if they could make my work quicker and easier. I have experience in educating developers. I've been teaching students PHP, Zend Framework(basic and advanced levels), MySQL, jQuery, Design Patterns and etc. I'm seeking to develop big and complex web applications using the last technologies and software development methodologies.
