Hi! I'm Ray. I'm a developer, also an instructor for several years, I love helping students learn to code and master software development.

I am now self employed developing web applications, network applications and chatbot using Python. The first program I sold was network application that help clients configuring, maintaining and testing thousands of multi-vendor network devices. I'm experienced with big projects like marathon’s online registration system, rental car management system, etc. I've worked extensively with Google App Engine, PostgreSQL and advanced system architecture design.

I've been a self-taught developer for many years, I know what is the most efficient way to learn a new skill. All of my courses have been designed from experiences, also in an interesting and simple way. I hope my courses are enjoyable for you and you will learn a lot from them!
