Hi! My name is David Armendáriz. I am ecuadorian.
I studied mathematics at USFQ (Universidad San Francisco de Quito). However, I love coding and that's why I transitioned to the software industry. I love to share my knowledge here in Udemy and in YouTube.
I hope you enjoy my courses as much as I enjoy doing them and remember: never stop learning!
