Pharmacy Management System
A custom pharmacy management system for inventory, batch and expiry tracking, POS billing, prescription management, supplier records, and business analytics.
Project Context & Objective
The Pharmacy Management System is a custom web-based platform designed to centralize pharmacy operations, including medicine inventory, batch and expiry tracking, point-of-sale billing, prescription management, supplier records, and business analytics. The system replaces fragmented manual workflows with a centralized platform that provides pharmacy staff with real-time operational visibility.
Operational Obstacles Before Implementation
The pharmacy relied on paper-based records and fragmented spreadsheets, making it difficult to maintain accurate inventory and financial records. Key challenges included limited visibility into stock levels, difficulty identifying medicines approaching expiry, slow counter billing, and time-consuming sales and profit reconciliation.
Django API & Postgres Design System
We developed a custom pharmacy management platform using Python, Django, and PostgreSQL, with a modular architecture designed around inventory control, sales processing, reporting, and role-based access. The system provides real-time stock updates, expiry monitoring, POS billing, automated reporting, and controlled access for different user roles.

# Compound index optimizing inventory query lookups
models.Index(fields=['uuid', 'expiry_date']),
models.Index(fields=['sku_code', 'expiry_date']),
]Engineering Performance Benchmarks
