No matter how you like to participate in developer communities, Pulumi wants to meet you there. If you want to meet other Pulumi users to share use-cases and best practices, contribute code or documentation, see us at an event, or just tell a story about something cool you did with Pulumi, you are part of our community.

Pulumi Community

There's a lot of small examples at <https://github.com/pulumi/examples>
I don't know of anything showing larger projects, but someone might have something.
