    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.

    Full-stack web developer and Python expert

    United Kingdom - Last active: 3 months ago - Tests: 6 - Portfolio: 1

    I'm a widely-experienced web developer, and a Python expert with around 5 years' experience using the language. (It's by far my favourite programming language for most tasks!) I'm very familiar with Django and have worked on a wide variety of Django-based sites. I'm currently working part-time for VODO (http://vodo.net), a platform for distributing independent media, where I'm heavily involved in developing the front- and back-end of the site. I'm very well-versed in front-end development; I know my HTML5, CSS, JavaScript (and CoffeeScript!) well and can comfortably and efficiently implement designs from scratch and integrate them with backend code. I'm a fast and enthusiastic learner - I'm currently working on learning Haskell and the fundamentals of functional programming, as well as learning some low-level programming. (I'm really interested in trying out Rust soon!) I'm currently studying Mathematics and Physics at Durham University, in the UK. This means I've had lots of experience with LaTeX and scientific Python, as well as being a fluent user of mathematics. I'd love to take on some projects where I can utilise my mathematical experience!
