I am also in similar situation, although there are some meet-ups, hackathons and of course #fccpune community members nearby.
To answer your question there are lot of ways you can collaborate, network and find mentors.
One resource i can share with you is the TravAndLos podcast episode no. 3 : How to find a mentor. This episodes explains in detail how to approach someone for mentorship. Also if u check their archive you will find topics that answer many of your questions.
The podcast is hosted by Travis Neilson (whom @ronbecker mentioned above) and Los Montoya.
Other way you can collaborate is by using Github. There is a nice article by @QuincyLarson How to land your first open source contribution, from your browser, in 15 minutes .
If you are interesting in a traditional Computer Science degree material check this link.
Here is a link to a discussion I started about Devtips community on this forum.
Internet is your friend, put it to good use. If u have slow internet connection, read articles on Medium , read blogposts, use every online resource available to you.
I hope this answer’s your question.
