From Production to Whiteboard

Most system design content teaches you what to draw on the whiteboard. This series teaches you why — from someone who's actually built these systems in production.

Each article takes a real-world design problem, walks through the requirements, the trade-offs, and the decisions that matter at scale — then frames it as how you'd approach it in a senior-level system design interview.

No hand-waving. No "it depends" without a reason. Just the thinking that separates a good answer from a great one.
