About Matteo
I am a professional Geodata Scientist working in the aerospace industry, where I use SQL and PostgreSQL every day to manage, analyse and optimise large-scale geospatial and satellite databases.
My teaching philosophy goes beyond learning SQL syntax. I help students develop the analytical mindset required to work confidently with real databases and solve practical data problems.
Whether you're preparing for university exams, technical interviews, a dissertation, or looking to improve your professional data skills, lessons are fully tailored to your goals.
My professional experience combines database management, data analysis, GIS, and Python automation, allowing me to explain not only how SQL works, but why different solutions are chosen in real-world projects.
Lessons are suitable for complete beginners as well as students and professionals wishing to improve their database expertise.

I've known Matteo for some time and have always been impressed by both his technical expertise and his ability to explain complex topics clearly.
He has a strong professional background in GIS, Python and SQL, and what stands out most is his practical approach to teaching. He focuses on helping students truly understand the concepts rather than simply memorising commands, making lessons engaging and effective.
Matteo is patient, well organised and always willing to adapt his explanations to the student's level and objectives. I would highly recommend him to anyone looking for a knowledgeable and supportive tutor.
