Christopher Okhravi - Invidious

Christopher Okhravi

I’m on a mission to answer a simple question: Which abstractions should be used when?

From the moment I learned my first abstraction, I was hooked.

This fascination continues to shape how I think about software and has led me to complete a PhD.

On this channel, I share practical frameworks, mental models, and real-world examples to help you make better decisions as a developer. Whether you’re a student, entrepreneur, or seasoned programmer, the right abstraction can make all the difference.

I make videos on:

1. Choosing the right abstraction.
2. Reducing complexity without losing flexibility.
3. Decision-making tools for scalable code.
4. When and why to make trade-offs.

If you’ve got a question, challenge, or story, email me—I’d love to hear from you.
