Inventory Management (Python, FastAPI, PostgreSQL, Redis, React, Docker) overview

An inventory and warehouse management system using FastAPI for a high-performance REST API handling stock levels, purchase orders, receiving, and multi-location transfers. PostgreSQL stores product catalogs, inventory transactions, and supplier data with strong consistency guarantees for stock level accuracy. Redis provides distributed locking for concurrent stock operations and caches frequently queried product data. React powers the warehouse dashboard with barcode scanner integration, pick-list generation, and real-time stock alerts. Docker enables consistent deployment across warehouse locations. Designed for logistics companies and e-commerce operations managing thousands of SKUs. The tradeoff is the complexity of maintaining accurate stock counts across distributed locations and handling edge cases like partial shipments and returns.
