Course · System Design
System design — one concept refined per week until you’re bulletproof.
Eight weeks, 1-on-1. Eight lessons walk you through the system design canon from first principles — grounded in how Netflix, Uber, Amazon, and others actually build — sharpening your core design thinking. Learn to reason, not memorize templates.
- Eight weeks, one 1-on-1 session every week.
- Eight lessons across the system design canon — estimation through observability.
- Every concept is anchored to real systems and real cases, not just diagrams.
- Optional add-on: four full mock interviews to rehearse the real loop.
The syllabus
8 weeks.
Optional add-on: four full 1-on-1 mock interviews — read-heavy, write-heavy / realtime, large-scale distributed, and an open-ended final — each with a structured debrief. Add them to rehearse the real loop end to end.
