(acquired by Yahoo!)Architected, Developed, and maintained web client and autoscaling service platform for ingesting, encoding, managing, archiving, and deploying VOD content.Initially brought on as infrastructure automation expert, Chef'd Evntlive's "cell" (defined as an haproxy/apache/jetty/etc unit) based multi-datacenter/region system using best practices.Developed custom live auto-scaling cloud transcoding system in AWS tested up to 20 mbit/s at 1080p using a combination of nginx-rtmp (to recieve a single rtmp stream), a custom forked version of ffmpeg (to segment video stream on keyframes), custom C zeromq application to fan-out chunked video encoding jobs, collect finished jobs, and insure proper alignment between different bitrates (for adaptive bitrate streaming), all with node discovery, configuration/role provisioning, and autoscaling handled by Chef, Ironfan, and Jenkins.Developed Chef/Ironfan code for managing various idiosyncracies of scaling up and down Cassandra clusters (for things like token placement, seed node discovery) in a Multi-datacenter configuration used in Evntlive's "Buzz" feature.Engaged in extensive TCP/RTMP packet analysis with hardware network taps (Ntap), congestion/latency simulators (Trinegy), and Wireshark to debug/diagnose/simulate venue connection issues over a wide variety of Satellite/cable/fiber drop/etc. situations. Analyzed performance of alternative TCP congestion control algos (such as TCP-Hybla) under various conditions.Chef, Ironfan, AWS, cassandra, percona, jetty, apache, wowza, ffmpeg, ruby, sinatra, git, haproxy, redis, solr, resque, java, nginx-rtmp, C, zeromq
