Covariance and Contravariance

About

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. Note: Some links on this channel are affiliate links.
