Vitalii K.

Vitalii K. Agency Contractor

Full stack web developer

Ukraine - Tests: 3 - Portfolio: 3

I'm professional web developer, working in this sphere more than 10 years. During my career I was concentrated on web projects, and mostly these projects were driven by PHP and MySQL on server, and Javascript on client. By years I was knowledgeable not only in these technologies, but also with different frameworks, which allow to make development faster. For example Zend Framework, Symfony and Yii for PHP. Jquery and Angular for Javascript. Also I tried to use some NoSQL technologies in replacement for MySQL. Of course I'm good in HTML and CSS. But right now I'm concentrating not only on the technologies, but I'm focusing on problems of my clients, and my goal is talk with client, understand their problems ans solve it successfully, using all my big experience and finally make client happy. And I think I'm successful in this, please just check feedbacks from my previous clients in the profile. I'm always open for new opportunities, so if you need any assistance, please just contact me. I can work in any timezone required, and I can travel for personal meetings to any country. As well I'm also in touch with small group of developers, who can help me with your project, in case you need any boost in development.
