Mobile Applications Developer (iOS and Android)

Ukraine - Tests: 2 - Portfolio: 12

During my 10+ years in software development, I have accumulated a solid experience working with various software technologies and programming languages. My career started while I was still studying in National University of Radioelectronics, where I got my Masters degree in Computer Science. At the moment I am focused on mobile applications development for iOS and Android. I have been working on iOS applications since the very first iPhone SDK was introduced in 2008. I am extremely detail-oriented and pro-active. I am not simply "providing development services" I solve problems for customers. I manage a team of software developers and I know how to get things done. I have a taste for good design and smooth user experience. A significant part of my career was dedicated to game development. I have an experience in creating solutions that are rich in graphics and have fluid animations.

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.
