### MPEG Engineer @ Innovacom Networks Inc
Jan 2000 – Jan 2003
•	Developed a high end hardware assisted MPEG1/2 encoder using the VxWorks RTOS that featured all the best techniques learned for MPEG encoding since the standard inception in 1994.
•	Designed real-time on-the-fly MPEG bit stream parsing and checking module used to store incoming network streams in an object oriented fashion using C++ language.
•	Architected highly optimized system for streaming MPEG streams to the network in push mode, being able to stream multiple parallel video streams seamlessly. 
•	Created highly optimized MMX assembly routines for bilinear and cubic interpolation, as well as highly optimized MMX deinterlacing code

### Project Coordinator and Main Developer @ FlasKMPEG
Jan 1999 – Jan 2002
•	Wrote open source FlasKMPEG transcoding program that ended being used as an official reference benchmark by Intel to measure multimedia performance with the Pentium 4 processor.
•	Teamed with Intel Performance Optimisation Labs, to implement assembly routines to support the Intel Pentium 4 platform.
•	Designed and assembled a full MPEG audio and video decoding system, including MPEG and Dolby Digital audio, and MPEG1/2 video.
•	Implemented successful new approaches to System Clock Reference discontinuities handling inside MPEG program streams. 
•	Implemented new routines for A/V synchronization able to work under severe clock jitter conditions.
