I turn sales, stock and customer data into decisions the business can approve, from merchandising to the supply chain, and I measure what each model returns.
Three demos, one stack
A fictional luxury house and a multi-brand beauty retailer with 40 stores. Each demo answers a question a director asks every week.
Architecture
01Merchandising · RetailStore Engine
The space register of a multi-brand beauty retailer. Every shelf, the brand renting it and why, its contract, sales and shopper traffic, and what a reorganisation would bring.
GCP · BigQuery ML · Gemini tool calling · ForecastingEnter the demo
02Retail media · DigitalShare of Voice
Every morning, the brand placements on public beauty retailer sites, read by Gemini. Each brand's share of the visible space, and the spend past which more money stops buying visibility.
GCP · Gemini vision · Agent Platform Pipelines · MLOpsEnter the demo
03Supply chain · PlanningDrop Planner
A luxury house's limited-edition gift set across 40 stores. Gemini reads the houses' real events, the order is the forecast raised by each coming event, and each plan is replayed against what sold.

Rigour, detail, and a taste for excellence.
Senior data scientist, six years in supply chain, operations and omnichannel. I listen to the business first, frame the project, take models into production with the data engineers, then measure the value they bring.
Today I build models, assistants and AI agents for the business. Tomorrow I would like to do it within a luxury house, where craftsmanship, the client relationship and attention to detail are measured at every step, from the workshop to the boutique.
