Learn System Design & DSA

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.
