Struggling with vague system design interviews or unsure how to scale your ideas? Whether you’re preparing for FAANG interviews, senior-level roles, or just want to grow beyond DSA—this session gives you clarity and depth on designing real systems.


What’s included:


  • 🧠 HLD (High-Level Design):
  • Learn how to break down complex products like Instagram, WhatsApp, or a scalable API gateway with core components:
  • Load balancing, sharding, caching, consistency trade-offs
  • Database design and choosing the right storage (SQL/NoSQL)
  • Asynchronous messaging, rate limiting, and more
  • 🧩 LLD (Low-Level Design):
  • Dive into object-oriented design and clean architecture of real-life problems like:
  • Design a Parking Lot, Cab Booking System, or E-commerce Cart
  • UML Class Diagrams, SOLID principles, and extensibility
  • Writing clean interfaces, classes, and identifying design patterns
  • 🚀 Live Design Walkthroughs:
  • Practice 1:1 with me as your interviewer—designing systems from scratch with whiteboarding + discussion.
  • 🎯 Framework for Interviews:
  • Learn how to ask clarifying questions, define constraints, and evolve your design step-by-step—exactly how top interviewers expect.
  • 🛠️ Real Engineering Scenarios:
  • Discussion of trade-offs in real-world systems I’ve worked on—covering latency, scaling, cost, and observability.


This session is ideal for mid to senior engineers, or even juniors preparing to level up fast and get design-ready.
