GStreamer Consultant for Webcam streaming from Android to Cloud

We are seeking an expert in video streaming with experience with GStreamer for hourly high-level consulting. We are developing a solution for a gstreamer based pipeline for streaming video collected from a USB webcam on Android and streamed to an AWS cloud endpoint. Implementation/coding is not required, this will be high level consulting on the design of the pipeline and the technologies/codecs/plugins to be used. The solution should be: 1) real-time (video should be received by the cloud in ~100ms or less from time of recording) 2) computationally efficient (the gstreamer encoder will be running on an android device) 3) simple (the solution should make use existing APIs and libraries without requiring too much custom code)
