• Integrate with external APIs (JSON-RPC, XML-RPC, REST) to enhance system capabilities.
• Ensure high performance of the system by optimizing database queries, implementing caching strategies using Redis, and ensuring optimal indexing and data flow.
• Implement role-based authentication and authorization mechanisms using JWT, OAuth, and RBAC patterns within NestJS.
• Follow security best practices to ensure sensitive data is protected, credentials are stored securely, and the system is resilient to common vulnerabilities.
• Work collaboratively with cross-functional teams to ensure seamless integration between different services and technologies.
