We host the best tutors. Quality of their profile, experience in their field. João will be happy to arrange your first Computer programming lesson.

About the lesson

My tuition method is adaptable to the needs and main difficulties of each student. I like above all to help students and, during this process, to create a good friendship.
As I always enjoyed helping colleagues during classes, I decided to apply so I could share my knowledge with more people.
My aim is to help students to enhance their technical and social skills so they are able to succeed both in their academic and professional career.
Many of the students I mentor go on to work as programmers and software development professionals, with others pursuing further study and careers in teaching and research.

I recommend João to explain programming. He helped me a lot in the work that I had to deliver. He always tries to get the student to try for himself to solve the problems and when the student can't, he gives clues and explains it step by step.

João is a tutor you can count on! he is always concerned about his students, during class time he always finds several different ways to teach if the student is having difficulty understanding something and if any doubts arise later he is always available to clarify, which shows the concern he has with his students and that he cares about their success.

Since beginning my lessons with João I not only got up to date on the subject matter but also clearly understood hard concepts in a short time. He has a clear, dynamic and practical way of explaining subject matters. I recommend him for the great teaching and explaining ability, but also for his ability to connect different programming subjects to not only your level but to the relevant areas you are studying.

João and I work next to each other in some days. He is extremely helpful and dedicated towards his students. I notice that he always tries to find a way to organize his schedule so that no one is left without help. I see him work, day after day, always committed to explain subjects in a simple and easy way to understand, as many times as necessary. He is very knowledgeable and has had excellent feedback from all the students who have him as a teacher. He really loves helping students overcome their difficulties, and that´s why i recommend him.

João, although not officially my teacher, is an attentive and helpful college colleague . He is a study buddy always eager to help. He explains the subjects clearly, with infinite patience, he never gets tired of repeating, in different ways, the subjects that weren't understood at first.
