The Redis community is hosting its annual hackathon, "Build on Redis," where developers can build new ideas using Redis and compete to win prizes totaling $100,000 USD. The event aims to bring creative minds together, provide a platform for developers to learn about trending technologies, and showcase their skills in a communal brainstorming environment. Participants will have the opportunity to meet and challenge fellow high-potential developers, propel their personal brand, train and practice for a fast-paced development environment, and win big awards and prizes. The hackathon is open to legal residents from specific countries and offers free training courses before the event.
