Modular code separates each pipeline function-data loading, cleaning, feature engineering, training-into well-defined modules. By following a single-responsibility principle and keeping configuration details in YAML, the pipeline in this project remains flexible and reusable. For instance, references to configs/transformations align each module’s parameters with typed dataclasses in dependencies/transformations.

Key Advantages

• Maintainability: Minimal changes ripple through code, as each module focuses on a narrow set of tasks.
• Parallelism: Orchestration tools like DVC or Prefect can run independent modules concurrently.
• Consistency: Each module logs its activity and uses typed configs, reducing guesswork when debugging.
• Scalability: Adding new transformations or new model variants requires only adding or modifying a module and its YAML, rather than refactoring monolithic code.

In short, embracing modular code fosters clarity, accelerates development, and strengthens reproducibility throughout the MLOps lifecycle.
