### Hey! I’m Avi, and I’ll teach you how to build!

I'm Avi, your new Python instructor and founder of The Codex.

Three years ago I was stuck. I wasn’t learning anything in my theory-filled CS classes, my friends took pictures of me sleeping in lecture, and I was questioning why I was even learning CS to begin with. I had ideas but I was clueless on execution.

After watching hours of webcasted YouTube videos, enrolling in course after course, and struggling to stay motivated, I finally obtained the skills to bring my ideas to life. I realized how lonely and gruesome this process was.

If you’re a student just like me, you know exactly what it’s like to be stuck in course hell. The best programmers of today learned by doing, not by reading syntax in a textbook.

## Savvy Students ❤️ The Codex

“CS classes at UW were overwhelming and full of theory. Through The Codex, I realized the power of Python programming, built _numerous projects for my resume_ and ultimately landed an internship at Amazon.“
