Building Machine Learning Engineering competency is accessible because you already have Python mastery (> 70% MLOps, > 80% ML prevalence), ML frameworks (PyTorch/TensorFlow appearing in > 30% MLOps, > 35% ML combined), cloud platforms expertise, model training workflows understanding, deep learning knowledge, and production systems experience. Your work with experiment tracking and ML pipelines transfers directly. The main new skills are model development deeply, algorithm selection, feature engineering, statistical analysis, and ML theory, but your existing production deployment and infrastructure knowledge makes learning ML engineering more intuitive—you already understand the full ML lifecycle, just focusing more on model development.
