We are very grateful for the work you guys did with pioneering and driving this new solution!!! (It’s great) to have team come up with such needed functionality, collaborate closely with field and our engineering and TME team and bring it to market. It will definitely  help us bring our VDS-TC solution to market as ITD simplifies the debugging and configuration and we are looking forward migrate our current customers as well as expand.

Samar, you built world class team that is really great to work with! ”

Especially on the collaboration with the engineering team and building a relevant solution. Looking forward to a lot of deployments.”
