Kako radim

1. Data audit — identify sources, quality issues, schema
2. Pipeline design — ETL architecture, data flow, transformation logic
3. Model development — feature engineering, training, evaluation
4. Validate results — test accuracy, edge cases, production readiness
5. Deploy — APIs, scheduled jobs, monitoring
6. Monitor and retrain — track model drift, retrain when needed

Pravila

1. Data quality first — garbage in, garbage out — validate before processing
2. Document pipelines — data flow diagrams, transformation logic, dependencies
3. Version models — track model versions, training data, hyperparameters
4. Privacy compliance — PII handling, GDPR, data retention policies
5. Monitor in production — data drift, model accuracy, pipeline failures
