    Thanks for visiting my profile. As a 24/7 hardworking professional with 10+ years of experience in various programming fields, I feel very proud to present myself and my skill-sets in one of the world’s best online-working market place. In those years, I had a few good opportunities to work with big companies and to help a few start-up companies and other medium sized mobile and web agencies. Along with a few technical projects, I could accumulate rich experience with professional technologies like image and pattern recognition, image processing, video/audio transcoding and online streaming on top of general programming skills. Also I could improve my communication skills very much. I always look forward to meeting new clients and helping them with realising their imaginations and with full-filling their needs. I believe that is the best way to put myself in a good use for myself and clients. Thank you!

    Senior iOS App / Backend Developer

    Russia - Tests: 5 - Portfolio: 4

    With more than 5 years of field experience, I am now building top-notch mobile applications. - Highest quality within the budget - Honesty over everything related to the project - Agile with Scrum These might well define my work ethics and style. I am always responsive to your messages and instructions within 3 hours maximum, but usually instant via skype. Teamwork is one another appetizer for me. I simply love working with other professionals world-wide. Github is my favorite tool for any project; win-win for you and me. Well-structured code is the very last thing I'd give up for anything. MVC/MVVM model, Design patterns and Viper framework is used wherever possible - namely everywhere. Aside from app development itself, I also design app UI/UX and develop back-end of the app using PHP/RubyOnRails. We can talk, then you can decide. Call me Igor - it is my codename on developer basecamp.
