I was honored to be welcomed at a prestigious institute like VESIT to speak and teach the students. This would not have been possible without the efforts of the team at CodeCell who organized the session. Special thanks to Mr.Sujitkumar Singh who was patient enough to follow this through over the last six months since February 2020 for planning this event. My humble thanks and gratitude to the faculty at VESIT and to the students who participated in the session. Talks and workshops like these enable and empower students with the right direction to their path on becoming tomorrow’s successful app developers!
