Brazilian w/ Spanish citizenship living in Ireland since 2019. As a native speaker, I can teach you how to write, read, listen and speak Portuguese for real, not like in books. Have a solid experience

Working with Marcello was a pleasure because he was completely committed to enhancing the procedure by utilizing his extensive Excel knowledge. He is incredibly passionate about teaching

Marcello provided me with the exact material and orientation that I needed. We worked with some real-life examples and mistakes that could happen in your day-to-day. I find his classes extremely useful and dynamic as he solves any doubt that I may have, and encourages me to practice! Excellent teacher if you want either to start from 0 or level up your skills in Excel.

I worked with Marcello at Ryanair and he was totally focused in improving the process using his great knowledge of Excel. Also, he was our "internal teacher" and he is so passionate about teaching excel to his colleagues.
It was a great experience to work beside him.

I never thought I could find someone that could explain complex things with a simply didactic. Marcello gave me classes of advanced formulas using my own content so I have learned in a real case and not something fictional. I'm a better excel user and I'm definitely going to get more classes with him in a near future. Best teacher I have ever seen.

Marcello is a wizard of excel. He knows everything! Very dynamic and professional, I definitely recommend him to everyone!
