Madurai has two active Google developer groups. GDG Madurai marked ten years with its 2025 DevFest, which covered Android, Flutter, Cloud and AI. It also streams live sessions and workshops on YouTube, so you can catch up even if a talk falls during your class hours. GDG Cloud Madurai focuses on Google Cloud and open source and brings together developers, sysadmins and data people.
If your online course covers cloud or DevOps, its meetups are a sensible place to try out what you have built. You will get honest feedback from people who run these systems for a living. Both groups invite members to co-host events. Offering a short demo of a course project is a good way to get noticed and to meet someone who could mentor you.
Independent community groups, listed for reference. They are not run by or affiliated with WebAsha.
