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?
