Are you preparing for software engineering interviews at top tech companies? Want to understand how applications scale from a few users to millions? This course teaches you system design through the lens of real-world distributed systems.
This isn’t a collection of short, surface-level videos for entertainment. This is a comprehensive, structured learning experience designed to build genuine understanding. Each lesson is carefully crafted to help you truly master the concepts, not just memorize them for an interview.
I’m a Software Engineer at Microsoft with over 5 years of experience working on the backend infrastructure of Microsoft Teams, a platform serving hundreds of millions of users daily. I’ve designed this course to teach you not just the theory, but the practical reasoning behind system design decisions.
What You’ll Learn:
System Design Fundamentals:
- How to scale applications from 0 to a million users
- Performance trade-offs: latency vs throughput, vertical vs horizontal scaling
- Back-of-the-envelope calculations for system sizing
- Message queues and event-driven architectures
Networking & Traffic Management:
- Core protocols: TCP, UDP, HTTP, and gRPC
- DNS and routing mechanisms
- API design patterns (REST, RPC, versioning)
- Load balancers, proxies, and API gateways
Service Architecture:
- When to use microservices (and when not to)
- API Gateways
Databases & Data Architecture:
- SQL vs NoSQL: choosing the right database
- CAP theorem in practice
- Indexing, replication, and sharding strategies
- Consistent hashing
Distributed Systems Concepts:
- Designing for fault tolerance and high availability
- Understanding latency percentiles (p90, p95, p99)
