Aspiring Professional
"When I first met Sharon, he seemed little introvert who barely socialized and was always glued to his laptop coding. But soon we became close friends, like brothers. He guided me throughout our college project which was a prototype of a robust AI-based Student Analysis, and his mentorship made the journey both fun and impactful. He is most fired up guy in the room when it comes to learning or doing something innovative."
