I am an Application Support Engineer at MathWorks. My job position allows me to explore different domains in MathWorks and find my target domain by doing projects in different domains.

My areas of interest are Signal processing and communications.

DISCLAIMER:Any advice or opinions here are my own and in no way reflect that of MathWorks.
