• Working on a Google-funded project, I contributed to open-source video codecs such as libvpx (VP9) and libaom (AV1) to make encoding significantly faster, saving compute costs significantly. I worked on core modules: partition, motion estimation, subpel processing, entropy coding.
• Led a team of engineers towards a successful delivery of a major project that consisted of multiple milestones relating to encoder/decoder speed-up, quality enhancements and critical support.
• Won 2 SPOT awards for technical contributions
