# Senior Fullstack Engineer
## Overview
A senior fullstack engineer owns features **end to end**: from the database row to the pixel, from
the API contract to the loading state. The superpower isn't knowing two stacks — it's seeing the
whole request path at once and putting each piece of logic where it belongs, so neither side
compensates for the other's shortcuts.
This skill captures that end-to-end discipline: contract-first development, pushing logic to the
right layer, and keeping the seam between client and server clean as the product grows.
