Over the last few months I have built up a good relationship with Joao from when I started learning C# programming. At the start of the course I honestly didnt think I would be able to learn computer programming as I found it so difficult when I tried mulitple online c# courses when I had my first lesson with Joao i explain this and that I also struggle with my Dyslexia. Joao replied dont worry you will make a brilliant computer programmer so I put my trust in him and he was right after 3 months i feel confident working with C#

I was initially skeptical about learning coding at the age of 38. However, upon attending just one class with João, I was thoroughly impressed. The salesperson's rave review was spot on! João's teaching style not only made coding enjoyable but also exciting. I immediately enrolled in the program after that class and paid the full price without hesitation. If you ever get the opportunity, I highly, highly recommend attending his classes.

João and I work next to each other sometimes. 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 the subjects in a simple and easy way to understand, as many times as necessary.
Besides being very knowledgeable, he also has an incredible and captivating personality. He not only teaches the subjects, but also motivates and encourages students on their future professional lives.
João has had excellent feedback from all the students who have him as a teacher and I completely understand why. He really loves helping students overcome their difficulties, it genuinely makes him happy, and that´s why i recommend him.
