About

Loadbearing takes one design pattern at a time from the load-bearing parts of real systems — the critical infrastructure where correctness and performance are both non-negotiable — and shows what experienced engineers actually chose, why it beats the alternatives, and what it costs.

Most system-design learning is theory, disconnected from how real systems are built. Here, every claim links to the exact source on GitHub, pinned to a commit. No hand-waving — just the production code and the reasoning behind it.

Written by an engineer with two decades building systems where mistakes are expensive.
