About Deepali
Hi! I’m Deepali — a Software Engineer and Algorithms tutor who makes Data Structures & Algorithms simple, logical, and beginner-friendly.
I’ve solved 1500+ DSA problems, reached 1840 on LeetCode (Top 6%), and earned a global rank of 24 on CodeChef.
These experiences help me explain even the toughest DSA concepts using patterns, intuition, and step-by-step reasoning — not memorized solutions.
