Open toolHow I work
01 · FRAME
Define the decision, the constraints, and the operating cadence. Most projects fail here before any modeling starts.
02 · MODEL
Build the system embedded with feedback loops and accountability. Not a notebook, not a prototype.
03 · DEPLOY
Move from a working model to a production decision system the team can actually run.
04 · OPERATE
Hand over with monitoring, drift controls, and the documentation to keep the system honest.
// Principle 01
Decisions are the product. Software is the tool.
Deployment
Your cloud
Model and pipelines run inside your VPC. No data leaves your account.
On-premises
Docker images running behind your firewall. No external calls at inference.
Handover
Monitoring, drift controls, and documentation so your team runs the system.

A few examples across forecasting, MMM, and operational risk.
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.
Key result
Full 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.
Key result
Forecast error: 38% → 24%
Proprietary Marketing Mix Model with budget optimization replacing intuitive allocation with data-driven decision making across multiple countries and touchpoints.
Key result
Strategic budget reallocation based on incremental response curves
Writing
The writing is there as proof of depth, not as a substitute for the offer.
A technical architecture for customer-brand affinity in physical retail: customer windows, lift and PMI, Item2Vec embeddings, graph construction, constrained layout optimization, and causal validation.
Department stores already have the data to rethink brand adjacency around real customer behaviour. The opportunity is not another dashboard, but a new merchandising decision system.
Pourquoi le R² évalue souvent mal un modèle de predicted Lifetime Value destiné à l'activation marketing, et quelles métriques utiliser pour piloter les segments en production.
Seven ML products, one retail team, and the question of whether to consolidate training into a single Vertex-native monorepo. The answer is conditional, and the condition is the whole point.
Why data science and AI platform projects fail on definitions, not on infrastructure, and how to let a real decision pull the data model into existence instead of waiting for the lake.
A staff-level field guide to predicted LTV for marketing activation: why ranking beats accuracy, why a directional model can beat an accurate one for seeding audiences, and where the whole thing quietly goes wrong.
