Today was my last day at StreamTheWorld. I spent the last 3 years there as the company C++ Tech Lead in charge of the company C++ streaming servers development. It has been a nice ride filled with challenges.These servers are used by over 1600 radio stations including AOL/CBS radios accessible through Winamp and Flash players.

Among my various realizations. There are:

• Scale and improve the performance and the reliability of the company audio/video streaming servers to the point where it can concurrently handles hundreds of thousands of live feeds every day in more than 25 countries, including during peak audience dayparts. The reliability and the quality of the server software have been proven to such industry leaders as CBS, Entercom, Multimedios, AOL and more. This represents 20x improvement over the original capacity.
• Added more functionality to the server by growing the server code base from 25K lines in June 2007 to 200K lines in only 2 years while improving robustness and performance.
• Designed and implemented a high performance targetted stream ad insertion system that serve end-user ads based geoip lookup. This system is now used by ESPN Radio on Internet.
• Design and implement a protocol stack to support Adobe proprietary protocol RTMP clients
• Add AAC support to the streaming server
• Improve Microsoft MediaPlayer and Silverlight support.

I will start my new job Monday next week. Visit back my blog or my LinkedIn profile if you are curious to learn for which amazing new employer I will be working for.
