About Matteo

I work as a Geodata Scientist in the aerospace industry, using SQL and PostgreSQL to query, clean and analyze large volumes of structured and geospatial data.
My lessons are designed to make databases logical, not intimidating. I use a professional digital whiteboard together with screen sharing to draw tables, relationships, JOIN paths and query flows before writing SQL.
This helps students understand the reasoning behind each query, not just memorize commands.

About the lesson

Lessons are practical and based on realistic data problems. The digital whiteboard is especially useful for SQL because it allows us to see the database structure first, then build the query step by step with a clear method.

• SQL foundations: SELECT, WHERE, JOIN, GROUP BY, HAVING, subqueries and CTEs.
• PostgreSQL, relational database design, table relationships, data cleaning and modelling.
• Window functions, aggregations, indexes and query optimisation for larger datasets.
• Support for university coursework, exams, interview practice, business datasets or your own database project

I took Italian lessons with Matteo and had a very positive experience.
He is a patient, friendly, and well-prepared teacher who explains the language in a clear and practical way.
What I appreciated most was that the lessons were adapted to my level and focused on real conversation, useful vocabulary, and everyday situations. Matteo always made me feel comfortable speaking, even when I made mistakes, and helped me improve my confidence step by step.
I would definitely recommend him to anyone who wants to learn Italian in an enjoyable and effective way.
