Marcello Mosse

After earning his degree and professional qualification, Marcello Mosse continued his journey by learning SQL. He first became a SQL Data Analyst. His studies in data analysis led him to learn Python. He became a Data Analyst and deepened his knowledge of Python’s specialized modules for data analysis: Numpy, Pandas, Matplotlib, and Scipy, along with data storytelling libraries and many other complementary tools. These skills allowed him to become first a Python data analysis specialist and then a Data Engineer.

Later, Marcello Mosse expanded his knowledge of Excel as a data analysis tool and began pursuing Python Institute certifications; he obtained the PCEP certificate — the first of four — which are useful for deepening both general and specialized programming with Python.

Building on this foundation, he later became a Data Scientist, applying machine learning techniques and predictive modeling to extract insights and drive data-driven decisions, further broadening his expertise in advanced data analytics and artificial intelligence.

"Python (50) Fifty" is a milestone in Marcello Mosse’s experience: good programming requires the constant application of theoretical concepts. Studying is not enough — it’s essential to apply what is read in books on a regular basis. Concepts must be repeated and internalized to build personal mental frameworks that are useful when solving real-world problems.
