• Solid skills with Redis and MongoDB (including query optimization basics).
• Experience with real-time data and WebSockets.

• Ability to work independently, take responsibility, and deliver results without micromanagement.

   

Nice to Have

• Experience with game mechanics or interactive applications.
• Familiarity with GraphQL.
