Web Developer

Russia - Tests: 2

I'm Zend Certified PHP Engineer (ZCPE) with over 5 years experience in web development. I participated in many projects, such as online booking systems (hotels, flights, train tickets etc.), online stores, CRM systems and others. I have also experience in writing API (SOAP, REST) for these projects. Unfortunately, almost all the projects I've worked on, are intended only for corporate clients and access to them is prohibited. So I can not refer to them in the portfolio because of NDA. PHP is not the only language that I use. I also had to deal with C#, Java and other popular languages. I always choose tools based on the task. My English is not so well, but I am a quick learner. You will enjoy working with me!
