Stop memorizing templates. Start designing real systems. A hands-on live cohort where every building block is followed by a real-world design walkthrough — until it becomes instinct.
Built by an engineer who’s designed systems at scale · 16 modules · 30+ real problems · 300+ diagrams
Passive tutorials don’t transfer to the whiteboard. This course is built on the pattern that actually sticks: learn a building block, immediately apply it.
Each weekend introduces a system design building block, then you use it live on a real design problem — with feedback.
Walk through how Instagram, Uber, WhatsApp, and Discord actually work — not toy examples or memorized scripts.
Not a recorded course. Limited seats, live discussion, personal feedback on your designs every session.
Learn to reason about tradeoffs, capacity, consistency, and failure like an engineer who has shipped at scale.
Not ready for the cohort yet? Start with these — the same material we build on in the live sessions.
Networking, storage, caching, messaging, consistency, scalability, distributed systems, observability, AI — every building block explained visually.
