12 System Design Patterns on 1 Visual Whiteboard 🔥

I got tired of Googling "when to use sharding vs replication" every time I prepped for an interview.

So I made the reference I kept wishing existed:

12 patterns, visually mapped
Netflix, Uber, Stripe: how they actually implement each one
The tradeoffs interviewers probe (so you're not caught off guard)
When to use it, when to skip it, and what breaks

One visual whiteboard. Zero tab-switching.
