- Implement CI/CD pipelines, automated testing, and reproducibility standards.
Integration & Interoperability:
- Design REST/gRPC endpoints for cross-language communication.
- Ensure compatibility with C#/.NET services.
Performance & Scalability:
- Optimize GPU/CPU utilization, batching strategies, and memory management.
- Plan for multi-model and multi-tenant scenarios.
MLOps & Lifecycle Management:
- Implement model versioning, artifact registries, and deployment workflows.
