2 Years of Effort, Packed Into One Powerful System Design Kit

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

Cheat Sheet – Quick revision material to brush up before the interview.

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.
