One thing to try might be contributing to Open Source?

Choose a project that looks interesting to you (ideally with a large community and modern tech stack) and join their Slack/Discord/Mailing List. You'll need to be patient and humble and it's going to take a while until you feel really comfortable, but read a lot, ask questions and try to contribute small bits here and there.

This will put you in touch with many interesting and experienced people, plus it's usually a great learning experience.
