What we’re about

The Chicago Java User’s Group is here to help the Java Professional. We want to make Chicago the ‘best’ place to be a Java developer, by offering a support network that allows each individual Java developer to grow! Its only purpose is to serve its community by focusing on three areas: - Learning about the Java Craft - Making a Difference in the Java Community - Growing as a Java Professional
Please join our communication channel on Discord:
Please find our session recordings on YouTube:
We would like to invite recruiters, staffers, head hunters, and all human resources personnel who are looking for Java talents in our meetup group, to join our LinkedIn group.

We are now on Mastodon! Please follow us:
