Looking for a full-stack web developer to build a fast, lightweight internal Inventory Management System for 8 physical retail storefronts. This is strictly for internal stock tracking and inter-shop transfers—no public storefront or payment gateways needed.Key Requirements:3-Tier Store Structure: Main Store (Tier 1) $\rightarrow$ Sub-Stores (Tier 2) $\rightarrow$ Sub-Sub Stores (Tier 3).1-Click Stock Transfers: Select a product in the Main Store, click "Transfer", select a destination store (Tier 2 or Tier 3), and enter quantity. The system automatically deducts from the Main Store and adds to the destination store.Automated Alerts: Low-stock notifications for Main/Sub-Stores, plus month-end alerts for "UNPAID" credit items at Tier 3 stores.Payment Status: Simple manual "PAID / UNPAID" toggle for month-end clearance tracking on Tier 3 transfers.Dynamic Store Management: Admin panel to add new Tier 2 or Tier 3 shops in the future without code changes.Tech Stack:Open to recommendations (Laravel/PHP, Node.js, Python/Django, etc.) paired with a clean, fast frontend and robust database logging.
