## Overview

QwikShift is presented as a location-based event-staffing marketplace: organizers post shifts and workers apply, with verification, payment escrow, invoicing, and dispute handling supporting a hire. The sampled server has database connection and middleware setup, but its API routes are commented out; the excerpts do not show a wired job-search/application workflow or how frontend modules are served. The graph preserves documented marketplace capabilities while limiting edges to evidenced calls and integrations.

Main entry points: [`webhooks/hiring-webhook.js`](https://github.com/kozzlost/qwikshift/blob/main/webhooks/hiring-webhook.js) (Hiring event handler), [`index.html`](https://github.com/kozzlost/qwikshift/blob/main/index.html) (Marketplace web page), [`payment/employer-onboarding.js`](https://github.com/kozzlost/qwikshift/blob/main/payment/employer-onboarding.js) (Employer onboarding), [`js/form-validation.js`](https://github.com/kozzlost/qwikshift/blob/main/js/form-validation.js) (Form validation)
