  4. MLOps & Production Engineering

    6 weeks
    • Learn containerization with Docker.
    • Understand cloud ML services (e.g., AWS SageMaker endpoints).
    • Master workflow orchestration (Airflow) and experiment tracking (MLflow).
    • Implement data validation and monitoring (Great Expectations, Evidently AI).
    • Online course: 'MLOps Specialization' by DeepLearning.AI
    • Cloud provider labs: AWS, GCP, or Azure free tier tutorials
