Patna has a GDG chapter that runs DevFest Patna. It is a good day to hear from working developers and to try a hands-on workshop that fits what you are studying online. IIT Patna also hosts Celesta, its yearly technical festival, and has its own GDG on Campus group, so the campus calendar is worth watching for competitions.
If you are leaning towards startups, STPI Patna runs an incubation centre for IT companies. It offers mentoring, seminars and workshops, and these are a direct way to meet founders. Many of them need people who can manage cloud servers, networks or security, which is useful early experience while you finish your course.
Independent community groups, listed for reference. They are not run by or affiliated with WebAsha.
