Course Overview
Design Real-World Systems with LLD, OOP, SOLID & Design Patterns in Python
Are you preparing for LLD/System Design interviews at top tech companies?
Do you struggle to convert real-world requirements into scalable class designs and OOP models?
Want to strengthen your object-oriented design skills using Python?
Welcome to “Low-Level Design (LLD): Using Python” your complete guide to mastering object-oriented system design and cracking LLD interviews with confidence.
What You’ll Learn
Core OOP concepts (encapsulation, inheritance, polymorphism, abstraction) applied to real-world problems
SOLID principles and how to implement them in clean, maintainable code
Popular design patterns like Factory, Strategy, Singleton, and more using Python
Class modeling, UML design, and converting requirements into code
When to use composition vs inheritance
How to approach LLD interviews: step-by-step system design, responsibilities, relationships, extensibility
Hands-on LLD projects like Parking Lot, ATM Machine Systems, Splitwise App, etc
Who This Course Is For
Python developers looking to level up their design skills
Students & professionals preparing for LLD/System Design interviews
Backend engineers aiming to write more modular and scalable code
CS undergraduates who want to build project-ready OOP skills
Bootcamp grads and self-taught devs breaking into software engineering roles
Why Learn Low-Level Design?
The high-level design gives the big picture but the low-level design is what you actually implement. It’s what makes your code readable, extensible, and interview-ready. This course bridges the gap between data structures and real-world system design.
By the end of this course, you'll be able to:
Confidently solve LLD problems in interviews
Write production-quality object-oriented Python code
Architect backend modules that are clean, flexible, and maintainable
Understand and apply LLD in real-world software development
Are you ready to build scalable systems and ace those interviews?

Excellent course for mastering Low-Level Design with Python! The instructor explains OOP, SOLID principles, and design patterns with clarity and real-world context. The hands-on projects like Parking Lot, and Splitwise made the concepts stick. Highly recommend this to Python developers, backend engineers, and anyone preparing for LLD interviews. Clear, practical, and interview-focused. Loved it!
