This repository is my personal space for learning and understanding system design, starting from the basics. I created this repo to document how I think about system design, not to dump finished answers or production-ready code. Most of the content here focuses on ideas, diagrams, and reasoning rather than implementations.
- Understanding how systems are structured
- Learning why certain design choices are made
- Exploring trade-offs instead of “perfect solutions”
- Breaking down complex ideas into simple explanations
My approach is:
- Learn concepts before tools
- Focus on thinking and reasoning, not memorization
- Write things in a way I can understand later
- Keep notes simple and interview-friendly
If I can explain something clearly in this repo, I know I’ve actually understood it.
Most notes try to answer simple questions like:
- What problem does this solve?
- How does it work at a high level?
- When should I use this?
- When should I avoid it?
- What are the trade-offs?
I also use diagrams and tables whenever they explain things better than text.
There is very little code in this repository.
When code appears, it’s only:
- Small examples
- Pseudocode
- Something that helps clarify an idea
This repo is about design thinking, not implementation details.
- Beginners starting system design
- Students preparing for interviews
- Anyone who wants a slower, clearer introduction to system design
If this helps future-me or someone else reading it — that’s a win.
This is an ongoing learning repo.
Notes may change, improve, or get rewritten as I understand things better.
