I worked with Sid in Virtusa on a couple of occasions. Sid is extremely sharp, logical, has a great sense of humour. He is a very honest person with a no nonsense approach and very calm in the middle of chaos. I found him to be a very effective leader: we both stepped into a difficult project when all hell was breaking loose and he managed the situation very well.

I have worked with Sid over the last 2 years both as a recipient of the products developed by his team and on a number of major pre-sales opportunities. I have found Sid to be a very conscientious and capable colleague, always willing to go the extra mile to deliver products against tight deadlines, both for client project work and regulatory deadlines. Sid has worked extremely hard to re-organise and implement common processes to the regulatory development team in an often challenging environment.

I would be delighted to work with Sid again in the future.
