You NEED to see these GraphHack projects!

THIS is what motivates me the most to do what I do. These projects are incredible!

Part of what’s awesome about this GraphHack, is its’ theme, Extending the Graph Ecosystem. Hackers were tasked to build something that benefits others in the community.

What am I so moved by it? Because this is a representation of what a community truly is!

Everybody wins, because everyone helps.

A collaborative and supportive ecosystem.

There’s more…

A major part my team’s (Neo4j Developer Relations) focus is to develop apps, tools, and integrations, that can be of value to the community.

We even have an internal program around it, Neo4j Labs, where we work with community members to build and create projects that others may find useful. These projects then have the opportunity to graduate and become formally-maintained and supported Neo4j projects.

This hackathon… gave our community the torch!

Not only do they drive the direction of what’s being built, but they actually built it! This, my friends, is true community initiative. ❤

(PS, if you didn’t participate, that’s ok! Just make sure you let the project-creators know if you liked their project! VOTE for your favorite project in the GraphHack Gallery!!!!!!)

GraphHack winners will go to GraphConnect 2020 (training included) to present their project in DevZone, provided compensation of hotel and airfare, get an exclusive invite to the Neo4j Ecosystem Summit, and will rub elbows with Neo4j executive staff.

How these hackers give meaning to my job — I can’t even ‘graphsplain’ it. ;)

Here’s a quick glance of the GraphHack submissions.
