Mac OS and Windows system development

I am a Mac OS X, Windows and Linux system programmer, developing low level and desktop applications. Was working on networking applications, 3d graphics (OpenGL) and parallel programming. I am using C++ to build my applications using frameworks like Qt (Cross-platform GUI development), Sciter/WTL/MFC (Windows) and Objective-C/Swift to create interfaces, preferring native (not managed by virtual machines) environments. Have a deep understanding of the Cocoa Framework, was building large scale applications for Mac OS X and iOS. Also working with electronics and building apps that interact with microcontrollers. Created drivers for such devices (OS X/Windows). I have created Apple Mail add-ins (reverse engineering of mail plugin API) and Audio Units. I have worked with x264/ffmpeg and OpenCV. I am good at solving problems. I like to think I have nice GUI design skills. I am attentive to details and consider myself a perfectionist.

A video player for dash cameras. Sorting recorded data chronologically and displaying it on a timeline. Apart from its main function - video playback, the application displays graphs recorded by the camera's accelerometer and follows the path, that the vehicle rode, on google maps, allowing the user to click on a maps marker and have the video playback started from that point, where the vehicle was located at the time. Used technologies: Cocoa, QTKit, WebKit and JSApi/JavaScript/HTML, Core Animation, Core Plot, designed a lot of custom controls and GUI components.

Yuri went the extra mile to understand the problem and analyze the existing code even before he was awarded the project. In fact at the time he was awarded he was prepared so well that he finished well before the deadline. World class! Thank you Yuri!
