    Good Day and thank you for taking a moment to read my profile!

    iOS, C++ Developer

    Ukraine - Last active: 12 days ago - Tests: 1

    Dear sir/madam, Hereby I would like to outline briefly my career. I started working as a software developer over six years ago, but it had been my desire for a long time before. I started my career as an assistant of a main developer. The project I was involved in was an application for Windows which collected statistics from a large number of websites and presented it in a user-friendly manner. Initially, my scope of work was to correct visual defects, but quite soon I was charged with correcting the logic of the application. The following project was a file converter into .pdf format. It involved development of a virtual printer which instead of printing a document saved it as a.pdf file. Besides, within this project we wrote a Windows program which could convert .pdf files into the .doc format. To save the content as a .pdf file a third-party library was used. At this project I was one of the main developers, namely I was responsible for developing the virtual printer. The next Windows program I developed was an application optimizing the work of the laptop battery. Again, I was one of the main developers and I was responsible for the work with devices, switching USB ports on or off, reducing the CD_ROM speed, etc. Besides, I developed a part of the graphic interface. Since 2009 I have switched to developing iOS applications. My first task in this role was to write an application of a SIP client for a lifesize camera. I implemented the SIP communication protocol without any external library and the RTP protocol. This project used h264 video codec. In order to decode it, I tried AVAssets and FFMPEG and succeeded in receiving and playing the video and sound. I also managed to transmit the sound, though transmitting a video signal appeared to be more challenging, as the camera could not receive large packets and AVAsset settings did not allow modifying the packet size. I also tried using FFMPEG but it had issues with performance. The following application I developed displayed the results of football matches. It included developing a server which would collect the statistics and send it to the application. The latter updated only the current data and saved it in a database to allow viewing of the statistics offline. Another project I participated in was a musical social network. The user could send his favorite song to his friend, and there was a possibility to comment and like the songs sent. The application also allowed the user to listen to the iTunes preview for the song. Besides, it included a radio: the user could make a radio station of any song and similar songs were played for him. At present, there is a similar feature in iTunes. The application we developed was called Musicgram, and you may find some information about it in the Internet. Meanwhile I took part in several small projects which are not worth discussing. My latest project was MC Remote (https://itunes.apple.com/ua/app/avizia-mc-remote/id811090778?mt=8). It was initially developed by another engineer, but I was in charge of bug fixing and writing new functionality for six months. The application provides control over a video-conference. There is a codec to which a display or several displays, several cameras and microphones and various devices are connected. This codec can create a conference, share the content etc. The iPad application connects to the codec over a special protocol and provides control over the conference, such as making calls, distributing video-streams between displays, share the content etc. Besides, a WEBRTC application was developed for a showcase which created a conference using the WEBRTC protocol.
