• Proven experience with scale-related challenges such as memory leaks and performance bottlenecks.
• Hands-on experience with cloud computing (AWS, GCP, or Azure) and distributed system architectures.
• Strong knowledge of databases (SQL and NoSQL), including MongoDB, Redis, Sqlite, or equivalents.
• Experience with Docker, gRPC, WebSockets, Microservices, Cron Jobs, and OpenTelemetry.
• Excellent debugging skills for complex, high-scale environments.
