Automated WMS system with microservice architecture

Database (PostgreSQL): "Single source of truth." It stores the actual quantity of goods.

API (FastAPI): "Brain" of the system. It processes requests, checks stock levels, and ensures that no one deducts more than what is available.

The management interface is implemented through a Telegram bot, allowing warehouse staff to work mobile, and the owner to receive instant reports in the audit channel.
Audit system (Channel): Transparent log of all actions for the business owner.
