Your Instructor


Gregorio Rojas
Gregorio Rojas

Gregorio has been in the software development field across a variety of industries since 1999.

His background allows him to not only provide Fellows with the best technical mentoring and support but also insightful and effective coaching.

He has been building software in the Southern California area since 2000 which has allowed him to build up a vast network of professionals in many tech and startup companies.

What’s your teaching style?

I push my cohort to "code their way to success". I want them to dig for answers and find every possible error they can so that they can understand how to deal with it in the future.

I believe in wrestling with code before I lecture about the given concepts. People are able to generate better questions and gain a deeper understanding when they have seen a piece of software in action.

Founding Sabio

I wanted to do Sabio for most of my career, although I never gave it a name. I started interviewing developer candidates for work very quickly in my career which gave me insights into the actual quality and expertise the industry had to offer.

It was not good. Things are not that much better but we are working to fix that 1 cohort at a time.

As a Founder and lead instructor I enjoy the very same challenges and rewards I used when I was working as a member of development team. I continue to mentor and "build" developers while looking to make the best impact on the company. Today, however, the two things are same.
