As there was a 10 hour time difference between us, it was critical for communication to be clear and efficient. Sagar excelled at this. He was never afraid to ask tough questions or provide his thoughts and ideas on how to improve the security architecture. These personality traits led to a very engaging and productive work relationship between us, and we quickly build out the PKI infrastructure and Cert model for the project.
