The challenge

What we walked into.

The retailer was managing product inventory across multiple warehouses and retail locations with no predictive capabilities. Replenishment decisions were entirely reactive -- stock was allocated based on gut feel, leading to stockouts of high-demand SKUs and overstock tying up capital in slow-moving products.

Product quality assurance and catalog management were major bottlenecks. New products required manual categorization, attribute validation, and quality review before they could go live across channels. The operations team was overwhelmed, creating a backlog that delayed seasonal launches and time-sensitive promotions.

Without demand forecasting, the retailer had no way to anticipate buying patterns or pre-position stock for upcoming seasons, promotions, or regional demand shifts. Every inventory decision was a guess that cost real money.

What we built

The engineering decisions.

Modern Full-Stack Architecture

We built a Next.js frontend paired with a Django backend, designed for real-time inventory operations at scale. The frontend delivers a responsive, fast inventory management dashboard while Django handles the heavy lifting -- API orchestration, ML model serving, and background processing pipelines. PostgreSQL provides the transactional backbone with optimized queries for inventory analytics across all locations.

ML-Based Demand Forecasting

Using PyTorch, we trained demand forecasting models on historical sales data, seasonal trends, external signals (promotions calendar, regional events), and product metadata. The models predict product demand 7-14 days ahead, enabling the retailer to pre-position stock before demand materializes. The system continuously retrains on new sales data to improve accuracy over time.

Product Quality Assurance & Catalog Management

We built an automated catalog pipeline that handles the majority of product onboarding. The system validates product attributes, detects incomplete listings, auto-tags categories and product types, and routes edge cases to human reviewers. What previously took the operations team hours now happens in seconds, with human oversight reserved for genuinely ambiguous cases.

Automated Reorder & Stock Optimization

The forecasting models feed directly into an inventory management system that automatically triggers reorder points, adjusts safety stock levels, and optimizes allocation across warehouse and retail locations based on predicted demand. Fast-moving SKUs are pre-positioned at high-velocity locations before seasonal spikes. The system also identifies slow-moving inventory and recommends markdowns or redistribution strategies.
