The decision to return to India in 2003 was his own, says Vishakantaiah.
"At that point, I really felt that here is an opportunity to work in India and put the country on the global silicon design map. This gave me the leadership opportunity to drive a project forward."
Even as the Dunnington team is now transitioning to the 'next big project', Vishakantaiah is also riding the learning curve.
A hardcore engineer, who metamorphosed into a leader, he is now mastering the art of engaging external systems such as the industry, government and academia, and how to influence the ecosystem.
This is what his job requires in India, apart from delivering many other complex projects in days to come.
