R - Power BI - Tableau - Python - SQL - Programming Lessons from an analyst on solving real-world problems.

I am very happy working with Yannis over the last year in courses like Mathematics and Economics. He explains in simple terms, and he's incredibly fast.

Ioannis helped me with Quantitative Methods. He's a mathematician with huge experience in a variety of fields and I am really lucky I have chosen him as my professor.

I needed Mr. Beka to guide me in analyzing data, setting up my models and developing algorithms to draw conclusions about the efficiency of specific hospitals in our country. We do 3 hours a week, and while the financials made me a little hesitant at first, I soon realized that the quality and speed of the course is 100% worth it. He takes out a large piece of matter in a short period of time and with great accuracy. Totally satisfied.

Well, I will talk about my relationship with Giannis, as due to my own choice I have chosen a full everyday life and I didn't always have time for lessons or reading. Giannis and I did maths, and I have to say that it seemed like Chinese to me at first, but through a few hours and a lot of patience on his part, I succeeded and scored a very respectable grade. Now, beyond the lessons and as a person, Giannis taught me a lot of things, as he is generally knowledgable and has also helped me in matters outside of mathematics. As a person, he is open-hearted and does not hesitate to share the knowledge he has spent countless hours acquiring. To those who hesitate because of the price, let me tell you that what you will get in return is worth much more and as I learned from Giannis, it is very important to constantly invest in your education, because this is what will give you an advantage in the future in your professional life his career.

I have only the best to say about Ioannis. He is an excellent professor with a lot of patience. His aim is not only to help it’s students to understand their difficulties but also to guide them towards knowledge.
