Learning With Chetna - Invidious

Learning With Chetna

"Speed" is the name of a game my Dear Friends …. Learn Data structure and Algorithm and System Design — without wasting hours.

I’m a software engineer with 12 years of industry experience.

If you're an experienced developer, you already know the challenge:
You’ve built real systems and shipped production code…
but interview prep still pulls you into long, time-consuming content for very little actual insight.

This channel is built to solve that.

*) What you'll find here:

→ DSA Quick Revision — core patterns, intuition, and clean implementations in 3–5 mins
→ System Design Masterclasses — deep-dive sessions (30–50 mins) covering real-world architectures, trade-offs, and scaling
→ AI Powered System Design Questions — applying concepts to real interview problems
→ Deep Tech Concepts — Kafka, Messaging Queues, Rate Limiting, Caching, Scaling, and more
