Check Out Some Global GraphHack Projects & Help Us Pick the Winners!

Global GraphHack 2019 kicks off today.

One of the things I love most about working with developer communities is that there’s so much open-handed support of one another. The developer ecosystem thrives on learning and helping through continuous contribution. Everybody wins, because everyone helps. 🙂

The theme for the GraphHack is “Extending the Graph Ecosystem”, which tasks the hackers with exactly that: building something that benefits others in the community.

While the prize is pretty cool…

GraphHack winners go to GraphConnect 2020 (training included) to present their project in DevZone, but also get compensation of hotel and airfare. They get an exclusive invite to the Neo4j Ecosystem Summit and will rub elbows with Neo4j executive staff.
seeing the creativity of the various projects and how aligned they are with the GraphHack theme, it’s easy to see our community really wanted to create something useful. There are some really impressive submissions in here! It’s definitely going to be difficult to select the winners.

Luckily for us, we have an awesome community that will help us pick! If you see a project you really love, go ahead and give that team your vote! They deserve it! You can place your vote in the DevPost Gallery.
