I develop and write protocol specifications to efficiently transmit data over SiriusXM's satellite broadcast system. I use various techniques to compress the data to accomplish this. These specifications are very detailed since they are used in the implementation of decoders in SiriusXM receivers. A balance must be maintained between minimizing the use of satellite bandwidth and the receiver's resource usage and code complexity.

I also design and develop the server-side systems which obtain the data from multiple providers over the internet and transform the data into a form described by the detailed protocol specifications mentioned above. These system are very robust and run 24/7 with almost no down time. I usually alternate between the programming languages C and Python. The choice depending on the specific requirements.

The most involved project for which I was responsible was an embedded MPEG-2 decoder for use in a system which does real-time processing of HDTV content. Implemented in C and x86 assembly language including Streaming SIMD Extensions.

A sampling of the projects on which I worked:

• MPEG-2 reference codec. Implemented in C.

• MPEG-4 experimental codec and algorithm development.

• Embedded software for DVD player.

• Targeted advertising for digital television.
