Never bet against System Design

Trust me, if you do, you will never crack any interviews

The reason you’re struggling with 𝗦𝘆𝘀𝘁𝗲𝗺 𝗗𝗲𝘀𝗶𝗴𝗻 interviews isn't because you haven’t studied countless case studies or designed a multitude of systems.

It is because you haven't mastered the core concepts.

I'm sharing the best resources for system design:

One project I would highly recommend, if you haven't done it already, is to build an HTTP web server from scratch.

System Design will be HARD for you until your basics are clear.

Here is a simple resource sheet I wish I had back in my prep days when I was just starting with system design (this would’ve saved me 100+ hours in wasted effort)

Dear Software Developers, a gentle reminder to:

- Learn DSA before jumping into Frameworks
- Learn Core JavaScript before React/Vue/Angular
- Learn HTML & CSS before Tailwind or Bootstrap
- Learn OOP before Design Patterns
- Learn Version Control (Git) before CI/CD
- Learn Core Java before Spring Boot
- Learn HTTP & APIs before GraphQL
- Learn Database Fundamentals before ORMs
- Learn SQL before NoSQL

Everyone wants to jump into shiny tools & frameworks. But it's the basics that make you a better engineer.

I created this guide:
Focused. Structured. Real-world backed.

It took me two years to build this guide while working as a software developer. I’ve divided it into three parts:

Fifteen-Day Preparation Strategy – Get prepped with all the necessary concepts in just 15 days.

System Design Concepts – Everything you need to know about system design.

50 Solved Questions – Detailed answers with HLD diagrams, LLD code, and in-depth explanations.

Trust me, this guide focuses on the 20% of topics that are asked in 80% of system design interviews.

I wanted to learn Software Engineering, so I watched 100+ videos on YouTube.

80% of them were a complete waste of time.

But this 9-playlist will teach you more skills than a 4-year degree.
