► Skipping the Algorithm Engineer III, I was directly promoted to a Senior Algorithm Engineer. The responsibilities also included leading the development as required► While in this role, I had re-vamped the training process for the machine learning algorithms like Deep Neural Net (DNN)► Carried out the training process for Machine Learning algorithms like.

► Continuing my responsibilities as a D.S.P. Software Engineer for supporting customers, the move to the Core Algorithm Team also required me to fix the issues found during deployment. ► Closely worked with the Voice Processing Team to help develop the enhancements required for the NS/AEC algorithms to cater a major customer with a very stringent deadline..

► Gained hands-on experience with calibrating, tuning and making code changes to algorithms. Including but not limited to - AEC, Multi Mic Noise Suppression, Audio Focus, AGC, Voice Equalization.► Supported customers on-site with both development and tuning activities.► Represented Audience for 3 weeks at a customer site in Korea coordinating an algorithm.

In less than a year with Audience, I had gained good in-sight of how the end product should be and how the algorithm is integrated along with the operating system to result in a mass production. While, I was working as a Systems Test Engineer, I started developing Algorithm specific tests to validate and characterize features like Acoustic Echo.

After having worked with the final product testing for about 4 months as an Acoustic test Engineer, I was assigned additional duties which included FPGA/IC based testing on a proprietary development/test board. In this role, I was responsible of testing the stability, functionality and performance before the DSP processor was integrated into a mobile.

As an Acoustic Test engineer, I gained hands on experience with carrier specific audio tests and product bench-marking. During this period I also developed automated data acquisition tools.Accomplishments included but were not limited to:► Developed MATLAB based tools to automate data acquisition for a multiple audio sources using switchers and Robotic.

Actively worked from February 2010 to July 2011 and continued to work/receive training and certifications during weekends and holidays until September 2012 (Immigration permitted multiple, specialization related jobs on OPT)During this period, I setup high-end audio visual equipment for various events on-campus/off-campus. This job involved working with.
