Learn System Design & DSA

Learn system design with practical lessons, interview frameworks, real-world case studies, and hands-on architecture projects.

Master system design and learn to build scalable, reliable software systems—from fundamentals to real-world architecture.Learn how modern systems work and prepare for software engineering interviews with practical lessons, design frameworks, architecture patterns, and guided projects.

WHAT YOU’LL LEARN :

• Client-server architecture and network protocols • Vertical and horizontal scaling • Load balancing and caching • SQL, NoSQL, indexing, replication, and sharding • CAP theorem, ACID, BASE, and consistency models • Microservices and event-driven architecture • CQRS, event sourcing, Saga, and circuit breaker patterns • REST, GraphQL, gRPC, rate limiting, and idempotency • Monitoring, observability, disaster recovery, and CI/CD • Capacity planning and technical tradeoffs

PRACTICE REAL SYSTEM DESIGN PROBLEMS

Work through guided designs for:

• URL shorteners • Chat and messaging systems • News feeds • Video streaming platforms • Ride-sharing services • Search engines • Notification systems • Payment platforms • Distributed key-value stores • Recommendation engines • Content delivery networks • Video conferencing systems

BUILD YOUR ARCHITECTURE SKILLS :

Explore 12 practical architecture projects with step-by-step requirements analysis, capacity estimates, data models, APIs, storage decisions, scalability strategies, and tradeoff discussions.

LEARN SYSTEM DESIGN PATTERNS :

Study load balancing, caching, database sharding, replication, consistent hashing, service discovery, API gateways, message queues, pub-sub, distributed tracing, service meshes, sidecars, and more.

PREPARE FOR SYSTEM DESIGN INTERVIEWS :

Use a repeatable interview framework to structure ambiguous problems, clarify requirements, estimate scale, communicate tradeoffs, whiteboard clearly, and present a complete design.

CASE STUDIES AND ADVANCED PRACTICE :

Go deeper with real-world-inspired architecture case studies, cloud service concepts, design documentation, distributed systems, consistency, consensus, distributed transactions, scheduling, and mock interview practice.

MORE ENGINEERING SKILLS :

• Software architecture principles • Design patterns • Clean code and refactoring • Technical writing and documentation • Resume writing and career growth • Interview and communication skills

Whether you are preparing for a software engineering interview, moving into a senior engineering role, or building production systems, Learn System Design gives you a structured path from fundamentals to advanced architecture.

Start learning system design, practice real architecture problems, and design systems with confidence.
