High-Level Design

High-Level Design is about zooming out and thinking in terms of systems, how different components interact, and how to design something that’s scalable, maintainable, and actually works in production.

Why I’m Learning This

So far, I’ve been more hands-on with low-level design and implementation. But as systems get more complex, it’s not enough to just know how to write good code but I also need to understand how to design systems that are reliable and can scale under real-world conditions.

That’s why I’ve started digging into high-level design. This space is my way of collecting everything I’m learning as I go.

What This Will Cover

Right now, it’s a growing collection. You’ll find:

• My notes from system design resources
• Architecture diagrams I’ve sketched while learning
• Questions I’ve explored (and struggled with)
• Concepts like load balancing, caching, database sharding, and consistency models
• Use-case breakdowns of common systems like URL shorteners, social feeds, messaging apps, etc.

A Work in Progress

This isn’t a polished library. It’s a learning log. I’ll keep updating this section as I study more, build more, and eventually start feeling more confident in designing large-scale systems from scratch.

If you’re learning HLD too...Welcome. Let’s figure it out.
