Google Apps Script Developer for Warehouse App

We are seeking an experienced Google Apps Script and Google Sheets developer to take over, stabilize, and complete an existing barcode-based warehouse management web app. The system uses a single HTML/CSS/JavaScript interface with a Google Apps Script backend and Google Sheets data tables. The app already includes parts of Dock Intake, Receiving, Put Away, carton labels, inventory tracking, Shipping/Pick, Cycle Count, Item Master, user roles, and activity logs. We need a developer who can audit the existing code, fix broken workflows, and complete remaining features without unnecessarily rebuilding the project. Immediate priorities include fixing Shipping order loading, stabilizing the Receiving → Put Away → Pick workflow, completing Pack/Ship functions, improving cycle counts and inventory controls, and repairing reporting/audit features. Experience with barcode scanning, carton-level inventory/allocation, Google Sheets data structures, label printing, and warehouse workflows is strongly preferred. The selected developer will receive a sanitized screen-by-screen requirements and test document, followed by sample code for review. Please include relevant Google Apps Script or warehouse/inventory examples, your hourly rate, availability, and your estimated time for an initial audit.
