"I mentored Nishan during his internship at 99X Technology. Nishan is a reliable and dedicated person in whatever the assignment given to him. I admire his quality of "following up" until the job is done. Apart from performing well at his main project, he also contributed a lot to the University Relationship initiative in 99XT. He did a tremendous job in coordinating a very successful session at UOM-IT faculty with the participation of 250+ students. I wish him all the very best in future endeavors."

"I have worked closely with Nishan during his internship period and his contribution to the project during that time is so valuable. He could easily learn the domain / technologies and processes and worked efficiently and effectively. Instead of just doing what he is asked to do, he went an extra mile and thought from each aspect while developing the system. This helped me a lot to find issues in the design and the functionality in advance. He is a person who says No for any opportunity he gets. Works with a smile and he has good team work skills."
