Systems Learning Path
⏱ Estimated time: 12-16 weeks at 10 hours/week
This is where vibe coders hit the wall. AI can generate a CRUD app, but it can't design a system that handles 100,000 concurrent users, fails gracefully, and doesn't leak data. That requires understanding systems.
The Systems track covers the hard stuff: concurrency, performance optimization, security, reliability, and architectural patterns. These are the topics that separate junior developers from senior engineers — and they're exactly what AI can't teach you through generated code.
8 modules of deep technical content, each with projects that force you to think about trade-offs, failure modes, and scale. This is the knowledge that gets you promoted.
Modules in This Track
Module
Systems Design Fundamentals
Load balancers, caching, databases — the building blocks.
Module
Advanced Systems Design
Distributed systems, consistency, partition tolerance.
Module
Concurrency & Parallelism
Threads, locks, race conditions — the hard problems.
Module
Performance Engineering
Profiling, optimization, and making things fast.
Module
Security for Engineers
Auth, encryption, OWASP — security isn't optional.
Module
Reliability & Observability
Monitoring, alerting, SLOs — keeping systems alive.
Module
Design Patterns & Architecture
Patterns that solve real problems, not textbook exercises.
Module
Data Wrangling & Everyday Code
ETL, scripting, and the practical code engineers write daily.
