## Description

Your goal is to build and ship the product that powers Lemrock's commerce infrastructure - with full ownership, from design to production. Concretely, you will:

 * Ship features end-to-end that reach millions of users - from data model and API design to the interface they interact with.
 * Scale and harden our backend as traffic, integrations, and product complexity grow.
 * Shape the architecture of the codebase - enforce clean boundaries, maintain modularity, and make decisions that compound as the team scales.
 * Move fast across the stack - backend, frontend, infra, data - wherever the highest-impact work is on any given week.
