- Implement and optimize caching solutions using Redis, Ignite, or similar technologies.
- Develop and integrate gRPC services for efficient communication between distributed services.
- Design and implement multi-tenant backend services, ensuring appropriate tenant isolation, scalability, and security.
- Containerize and deploy services using Docker and Kubernetes.
- Contribute to CI/CD pipelines and automated deployment processes.
- Write unit, integration, and performance tests to ensure application reliability and quality.
- Apply appropriate design patterns, clean code principles, and software engineering best practices.
- Participate in code reviews, technical discussions, and architectural decisions.
- Perform performance profiling, troubleshooting, and tuning to optimize services under heavy workloads.
