We do an annual Mumbai Hackathon (https://mumbaihackathon.in) which is great for college students and they get introduced to FOSS. There are lots of things people can build: https://medium.com/@rushabh_mehta/project-ideas-for-mumbai-hackathon-2019-22d17465f294
If there is significant prize money, people will join. Bangalore is the right place to do this. We can offer prize money from Frappe / ERPNext Foundation. Anyone willing to volunteer to take the lead?
