Lanexas contribution

Domain architecture, stock and reservation modelling, integration design, technical leadership, code review, and release planning.

Outcome

Orders and inventory were consolidated in one system. Asynchronous integrations no longer blocked core operations, and repeated event delivery did not create duplicate orders.

AI involvement

Demand forecasting extended the inventory platform from reporting current stock to predicting demand, stockout risk, and practical replenishment quantities.

Delivered AI capabilities

  • 01Demand forecasts by product, warehouse, and region using sales history, weekday, seasonality, promotions, holidays, and trends
  • 02Projected demand over 7-, 14-, and 30-day horizons together with estimated stockout probability
  • 03Smart replenishment recommendations combining forecast demand, current stock, and safety-stock targets, exposed through a forecast API

Production path

Order events → Kafka analytics pipeline → Python demand model → forecast store → Go inventory service and API

What was delivered

  • 01Warehouse and sales-channel synchronization
  • 02Stock reservations, order imports, and fulfilment states
  • 03Idempotent event handling, role-based access, and audit history

Technical stack
