System Design Fundamentals - HLD and LLD

Master software architecture by learning practical techniques to create scalable high-level and low-level system designs

What you'll learn
- Understand system design fundamentals—Gain clarity on key concepts like scalability, availability, consistency, and performance.
- Master high-level design (HLD)—Learn to architect scalable systems by breaking them into modular, robust components.
- Excel at low-level design (LLD)—Develop proficiency in translating requirements into precise, maintainable software designs.
- Practice real-world problem-solving—Apply system design concepts through practical examples and case studies.

Requirements
- Basic computer science fundamentals and basic programming knowledge in C/C++/Java/Python would be sufficient

Description
This course provides an in-depth exploration of system design fundamentals, focusing on bothHigh-Level Design (HLD)andLow-Level Design (LLD). Designed for software developers, engineers, and architects, this course helps learners build a robust foundation in creating scalable and maintainable software solutions.

In the HLD modules, students will learn how to break down complex systems into clear, modular components, select appropriate technologies, handlescalability, and manage trade-offs such asconsistency,availability, andpartition tolerance. Practical examples and case studies, including popular applications like YouTube and Netflix, will illustrate real-world implementation strategies.

The LLD modules dive into detailed design patterns,class structures,object-oriented programming principles, and best practices for writingclean, efficient code. Through interactive examples, students will practice converting high-level architectural designs into concrete implementations thereby building a solid foundation for designing software.

By the end of the course, students will confidently approach system design interviews, effectively architect scalable applications, and understand critical design concepts such as consistent hashing, caching strategies, message queues, and databases.

Join this course to become proficient in both high-level and low-level system design, empowering you to architect reliable software systems at scale and excel in your software engineering career with practical, industry-ready skills learned from real-world scenarios.

Who this course is for:
- Software developers aiming to strengthen their skills in system architecture and design
- Engineers preparing for technical interviews at top tech companies requiring system design knowledge
- Experienced developers who want to transition into software architecture or senior engineering roles
- Computer science graduates and professionals seeking to understand how large-scale systems are built and operated
