Winning a competition

The Indian government introduced an open competition to develop a video conferencing app which have features like conferencing, screen sharing, recording, chat, end to end encryption, etc. The winning prize is $130K. After doing some research, I have found OPENSIP, GNUSIP, and JITSI. I’m not sure which way to go but JITSI looks promising. I would like to know if JITSI is the right approach to do so and also if anyone is interested in collaborating in this competition, we would love to have his/her as member. Please remember that the winning prize is worth participating in. Please check the link for a detailed description of the competition, the last date of registration is April 30, 2020.
