CIR Approval — HEC Paris — 15+ years — Ex-Head of Data & BI (€100M Revenue)
🎯 What I do in 2026
Data & AI Solo Squad: I deliver alone, in 4 to 10 weeks, what a data team of 3 to 5 people used to deliver in 6 months. Stack Claude Code, MCP, Python, dbt, Airflow, Snowflake. 10x productivity on three projects where Large Corporations lose the most time:
✅ Audit and refactoring of data technical debt — dbt models, ERP migrations, legacy pipeline redesign. Recent case: redesign of a strategic datamart for a €1.6 billion group — 12,500 lines of code in 5 days, preliminary design document and human supervision on each pull request, zero downtime.
✅ Reverse engineering of legacy reports — those gas factories no one dares to touch (Excel 30 tabs, orphaned scripts, unstable n8n), re-engineered under Airflow + GitHub + dbt in two weeks.
✅ Industrialized Webscraping + AI enrichment — custom external databases (price monitoring, competitive intelligence, supplier data) with LLM classification, for Marketing, Purchasing, Strategy, and M&A departments.
💼 The rare aspect of my profile
Ex-Head of Data & BI at Atida / Santédiscount (€100M revenue), where I designed and marketed a data monetization offering to major pharmaceutical and cosmetic laboratories — Pierre Fabre, L'Oréal, Sanofi, Procter & Gamble. I understand data from both the producer's AND the Large Corporation buyer's perspective.
🚀 Why engage me
You're not looking for another technical expert, you're looking to shorten your timeline. Senior daily rate, delivery at team speed: zero multi-consultant coordination, zero long onboarding, zero IT service company dependency. I speak the language of your leadership: 8 years in investment banking (HSBC Hong Kong, Pictet Singapore, SocGen M&A), then 4 years interacting with CEOs / CMOs / CFOs of major laboratories.
