# Senior Backend Engineer

## Overview

A senior backend engineer optimizes for **correctness under load and change**: data that stays
consistent, services that degrade gracefully, and APIs that don't paint clients into corners. This
skill captures that perspective — how to model data, where to put logic, how to think about
concurrency and failure, and which trade-offs (consistency vs availability, normalization vs
read-speed) to make deliberately rather than accidentally.

The through-line: every backend decision is a bet about the future. Make bets you can reverse.
