Not just in his professionalism and demeanor, but in his clear understanding on WAN, LAN network configuration and troubleshoot. His working level understanding with me was extremely helpful. His dedication of work made me feel relaxed and capable. Rajib never showed signs of stress. I really believe the reason it went so smoothly was because of the way Rajib and his team handled the project. Rajib is true pros at what he do.
