    Ukraine - Last active: 2 months ago - Tests: 3 - Portfolio: 8

    Hi, my name is Kyrylo, and I'm oDesk Verified Mobile Applications Developer. I mainly focus on iOS development with Rubymotion, but also can work with Objective-C and Swift. Since almost every mobile project needs a server to store data or authenticate users, I also have a lot of web-development experience, including back-end development (Node.js, Ruby on Rails) and front-end development (Angular.js, Ember.js). Lately I was working on a wide range of projects, from social apps to business apps with huge databases, and from small utility apps, to games. I was working on applications like PackPoint or TradeGecko that were mentioned by TechCrunch, Lifehacker, TheNextWeb, 9to5Mac, Washington Post, L.A. Times and others. Some other apps were featured in App Store, others have 60k+ monthly users.

    Philippines - Last active: 07/26/2013 - Tests: 1 - Portfolio: 6

    In my 10+ years on the IT Industry, I have participated on different kinds of projects that demands specific roles. There are instances in which I was the one to design the architecture of the application and manage its implementation. While there are some that requires me to follow an existing architecture and work with other developers on the implementation. This shows that I can either work alone and manage my own resources or be a part of a development team. I have already helped companies develop different types of applications ranging from simple dynamic websites up to a full-blown Desktop/Web application using the .Net Framework. I primarily use C# as my main programming language. One of the most important thing on a virtual work environment is to establish a good communication with the client. I do this by having a daily/weekly meetings to keep the client up to date with the things that I’m working on. It’s already been 4 years since I started doing Telecommuting (Home-Based) Jobs. And during that time, I have learned how to manage my time efficiently and deliver products as expected by the client.
