Core Product Architecture & Engineering Decisions
How we prioritized database design, hardware integration, and offline resilience for 22 business types in Bangladesh.
Enforcing Automated FEFO (First-Expiry-First-Out) over FIFO/LIFO
Pharmacy & RetailThe Real-World Problem:
Bangladesh pharmacies face heavy financial losses and regulatory penalties if medicine boxes nearing expiration remain buried behind new stock on shelves.
Architectural Choice:
Engineered batch-level inventory tracking in PostgreSQL where the POS barcode scanner automatically prioritizes and deducts the batch with the nearest expiration date (FEFO), regardless of arrival order.
Engineering Trade-Off:
Added complexity to sales returns and stock transfers since each line item must preserve its exact batch number and manufacturer lot ID.
Measurable Impact:
Eliminated shelf expiry losses for participating pharmacies, with automated amber alerts at 60 and 30 days before expiry.
