Memgraph’s First Hackathon

Memgraph’s First Hackathon

July 6, 2021
Sara Stetic

Last week we gave you a sneak peek into a fun project designed to experience what other developers are going through while using Memgraph - our very first Hackathon!

Every engineer in Memgraph works hard on building Memgraph products within their team. However, the majority of engineers have not actually used Memgraph for their projects. Almost no one built an app with Memgraph before, and yet, we expect other developers to have a good and productive time using it. To get a better understanding of what other developers and engineers are going through while using our products, we needed to put ourselves in their shoes.

Walking a Mile in the User's Shoes

A hackathon was the perfect playground for discovery where participants had the opportunity to get to know each other better by taking on new roles and breaking out of their daily routine. To have enough time to build something cool, day-to-day work was paused, and for a whole week, everything else within the company was focused on a hackathon. Engineers from different departments and with different skill sets were put together through random pairing, and after teams were formed, it was time to decide on ideas and start hacking. The rules were simple - build cool app examples that are using Memgraph. A couple of data sets were already provided, but teams could have chosen anything they wanted. We were surprised to see how the hybrid model worked well in this situation. While most team members stayed at home and focused on their app, some of our team members wanted to meet onsite, which was possible thanks to our shared co-working space in Zagreb.


The Final Projects

Here’s an overview of the projects each team did:

  • 405 found: Sentiment analysis on a stream of Reddit comments
  • Entropy Crusade: Slack bot that helps you understand and influence your slack community
  • Feature, not a bug: Insights from Orbit extracted data on users and their activities
  • Boolean Pundits: Recommendation engine for people searching for new songs they will enjoy based on the songs they currently listen to, a.k.a. Spotify 2.0
  • The Hip Trojans: Trainsplotting, a graph-driven railway system monitoring application

After a week of intensive coding, the last day was reserved for presentations. And what makes a good hackathon? Awards, of course! There were five categories - best graph model, best graph visualization, best graph algorithm, best presentation, and best overall app. Kudos to the winning team, 405 Found, on their streaming app. This may be our first Hackathon, but with how everything went down, it definitely won’t be the last one.

In the next couple of weeks, each of the projects will be published on the Memgraph website for all the developers to have a look, check them out, and use them as cornerstones for their own apps. In order to learn more about different apps using Memgraph, stay tuned and follow Memgraph!
