Expert media software developer. Ffmpeg, webrtc.

A C/C++ low level developer with skillset and experience centred around high-performance media streaming and processing tools. Typical projects are in the field of video/audio streaming, conversion, analysis, transformation and delivery. For example: low-latency live as well as recorded video mixers, WebRTC solutions, AI/neural nets integration, passthrough ads overlays, object recognition and classification on live streams coming from webrtc/browsers, desktop clients, security cameras and rtmp/rtsp/ONVIF feeds, stream composition, conversion between hard-to-combine formats or protocols. Low latency screen sharing apps. Deep understanding of HLS as well, earned by implementing some customer ideas that exploited this protocol to the limit. With 25 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. Extreme example of it is that i have a fully in-house built WebRTC implementation in C++ built using libavformat, libssl, libdtls, libnice, and hand-hacked packetisation of H264 according to RFC 6184.. 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). Famous and big of my customers include Cedexis, Pubnub, Kargo Global (the ad empire, not the GitOps or a trucking company with same name), and Kobiton. 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)
