Who is a Machine Learning Engineer?

A Machine Learning Engineer is a specialist who designs, builds, and deploys ML models. Unlike data scientists, who focus on data analysis and insights, ML engineers optimize algorithms for scalability, integrate them into applications, and ensure model performance in production environments.

Key Responsibilities of an ML Engineer:

Designing and implementing machine learning models
Preprocessing and analyzing large datasets
Fine-tuning algorithms for optimal performance
Deploying models in production environments
Collaborating with data scientists, software engineers, and business teams

Step-by-Step Guide to Becoming a Machine Learning Engineer

Step 1: Master the Fundamentals of Programming

ML engineers need strong coding skills, particularly in Python and SQL. Python is the dominant language for ML due to its extensive libraries like NumPy, Pandas, Scikit-learn, and TensorFlow.
