Hello, I'm Gabriel, a professor by vocation, I have always been involved in teaching since my beginnings. I have more than 20 years in university education in the subjects of programming and algorithms. I can help you from the first steps to the most advanced subjects.
The programming languages I teach can be Python, Java, C, C#, Javascript among others. In addition to frameworks highly used in today's industry.
Programming is part of my being and I like to spread it.
Programming can transform you. I am here to guide you in every step, giving you the necessary tools for your growth. Together, we will make learning an enriching and exciting experience.
I am interested in the student taking away more than the specifics of the programming language, to have a comprehensive understanding.
As a university teacher, I can also help you with the delivery of programming practices (practical work, exercises, etc.), with a clear explanation of their resolution.
Let's discover this world together!

Muy buen profesor, muy recomendado!
Mucha paciencia, y para todos los niveles, usa muy buenos ejemplos para cada situación complicada de comprender.
(En mi caso para lenguaje de programación JAVA)
Sin duda una experiencia muy agradable.

Mr. Gabriel Barrera has a lot of patience and was able to make me understand concepts very clearly, he also was able to detect errors in places that are hard to detect. For those who need to understand excel, I fully recommend studying with professor Barrera ! :)

Llevo dos clases con Gabriel y estoy muy contenta. Explica todo de manera clara y se centra mucho en las necesidades del alumno para programar las clases y el contenido que es relevante en mi caso. En mis clases me está ayudando a corregir algunos trabajos y poquito a poco me explica los cambios necesarios para hacer el código más optimo y me explica la materia a través de dichos trabajos. Es excelente.
