Architecting a Modern POS System: Inventory, Barcodes, and Roles

A Point of Sale (POS) system is more than just a calculator—it's the central nervous system of a retail business. Architecture is everything. I specialize in building custom POS and inventory solutions.

Core Architectural Pillars

• Offline-First: The system must work even when the internet goes down.
• Atomicity: Transactions must be all-or-nothing to prevent data corruption.
• Granular Roles: Restrict sensitive actions (like refunds) to managers only.

I build these systems using .NET Core for the speed and Firebase for real-time cloud analytics. See my inventory management success stories or discuss your retail needs.
