Expert media software developer. Ffmpeg, webrtc.

I provide solutions in the field of video streaming, webinars, video chats, video recording and post-processing, collaging, video editors and online video streaming processors, as well as screen capture/sharing, remote control, application sharing and whiteboard applications for both web, mobile, and desktop downloadable apps. With 18 years of software engineering experience and a large collection of ready and owned, available for adaptation and integration source code, i provide cost-efficient solutions for a wide range of customer cases. This made me a top #1 Upwork contractor in European Union(*). Prime example of my work is WebinarHD - a popular webinar platform wholly built by me and my team, employing Single Stream technology which combines all streams comprising the webinar broadcast such as webcams, screen shares, documents, live streams, as well as audio streams from mics, into a single composite stream to broadcast to attendees saving bandwidth and improving quality and synchronisation. Big success in sales, in active use by over 1100 webinar hosts, running regular webinars on every topic from marketing to religion. Also, i have a huge experience building networking-intensive applications. A lot of experience with pubnub, rtmp/rtmfp, webrtc, building custom binary protocols and implementations (both TCP and UDP based, for example: hand-hacking DNS requests). My customers include Cedexis and Pubnub. Some of my less-recent and somewhat obsolete areas of knowledge are the Adobe stack (Actionscript 2/3) and low-level undocumented file format analysis and synthesis: 7 years as a head of all development for OfficeRecovery, inc. (now part of Axcient) (*) Based on total amount earned. Excludes contractors staffed by agencies and contractors with profiles hidden from public view.
