I was a Security Specialist for software security and cryptology [2006 to 2008]. Following, I joined a firm under a statutory board involving in National Security Frameworks as a Senior Consultant [2009].

I would like very much to meet altrulistic, courageous, purposive, perspicacious people who are seeking to work on a noble cause. It is a very nourishing experience to share life lessons with compassionate, passionate people who are relentlessly seeking discoveries and growth.
