Machine Learning Engineer:
A beginner ML Engineer works on building and deploying simple machine learning models by writing Python code, using libraries like Scikit-learn or TensorFlow, and integrating models into basic applications. The role focuses on understanding how models move from notebooks to real systems, learning data pipelines, APIs, and version control, rather than advanced research or complex math.

Data Scientist:
A beginner Data Scientist focuses on cleaning and analyzing data to find patterns, create basic predictive models, and present insights using charts and reports. The role emphasizes statistics, data analysis with Python or R, SQL querying, and clearly explaining results to support decisions, not large-scale deployment or production systems.
