Searching for effective abstractions. I've been fascinated by abstractions for almost two decades. This 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 effective abstractions. 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.
