Ce que je fais
Systeme de prevision en production, rythme 30-90 jours.
Prevision de la demande, scenarios, stocks et decisions operationnelles sous incertitude.
Systeme decisionnel de pricing avec elasticite, contraintes et arbitrages portefeuille.
Elasticite, optimisation tarifaire, arbitrages portefeuille et aide a la decision commerciale.
MMM et allocation budgetaire avec revue mensuelle.
MMM, courbes de reponse, allocation budgetaire et decisions partagees finance-marketing.
Workflow decisionnel auditable, logique metier explicite et transfert clair.
Workflows IA, recommandations et logique metier quand controle et auditabilite comptent.
Ma methode
01 · FRAME
Definir la decision, les contraintes et le rythme operationnel. La plupart des projets echouent ici, avant tout modele.
02 · MODEL
Construire un systeme integrant boucles de feedback et responsabilite. Pas un notebook, pas un prototype.
03 · DEPLOY
Passer d'un modele qui marche a un systeme decisionnel que l'equipe peut faire tourner en production.
04 · OPERATE
Livrer avec monitoring, controle de drift et documentation pour garder le systeme honnete.
// Principle 01
Le produit, c est la decision. Le logiciel, c est l outil.
Prevision, pricing, MMM et workflows IA decisionnels — concus pour l operation, pas pour la demo.
Le cadre Artometrix: des modeles integres aux contraintes, aux boucles de feedback, a la responsabilite et au rythme operationnel.
Cas selectionnes
Quelques exemples couvrant prevision, MMM et risque operationnel.
A production-oriented recommendation system that guides customers through emotionally loaded floral purchases — using a deterministic state machine with LLM components constrained to intent parsing and rationale generation only.
Resultat cleFull guided purchase flow: delivery validation, persona selection, budget extraction, curated recommendations with auditable scoring
Multi-SKU demand forecasting pipeline for 30+ products across 100+ duty-free locations with automated monthly updates.
Resultat cleForecast error: 38% → 24%
Proprietary Marketing Mix Model with budget optimization replacing intuitive allocation with data-driven decision making across multiple countries and touchpoints.
Resultat cleStrategic budget reallocation based on incremental response curves
Ecriture
Les articles servent de preuve de profondeur technique, pas de substitut a la proposition de valeur.
Enterprise AI systems often work at the first level of granularity, then become fragile when the business asks for more precision. A field lesson from pharmaceutical supply optimization on why incremental architectures matter.
Raw latency and perceived latency are different engineering problems. Production GenAI systems feel fast when they expose progress early, overlap backend work, and avoid silent waiting.
What it actually takes to build a production forecasting system for luxury demand at SKU level: decomposing products into shared attributes, designing hierarchical aggregate features without leakage, handling intermittency with Tweedie and hurdle objectives, and forecasting in a way finance can use.
Intelligence-native systems need agent access to decision artefacts and feedback loops. Why context, not models, is the differentiator — and how MCP, traditional ML, and versioned artefacts fit together.
A field perspective on hierarchical forecasting in luxury retail — where ultra-premium SKUs sell fewer than 100 units a year and finance cannot ignore them.
Markdown planning explodes when weeks, events, discount levels, and phases are modeled as separate dimensions. Collapsing each week into a single state turns it into a clean optimization problem.
