About Jean-Brice

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.

    HUMAN RESOURCES
    June 2024 - Today (2 years)
    Toulouse, France
    At a French temporary employment group (€1.6 billion revenue), mission as Senior Data Analyst on high-stakes projects for commercial steering, AEI regulatory compliance, and decision-making foundation industrialization. 636 PRs merged, 25 structural PRs, ~125,000 lines of code touched over 21 months.

    🤖 Redesign of a strategic datamart in AI-augmented Solo Squad mode: 12,500 lines of code delivered in 5 days on a datamart consulted daily by the sales department, preliminary 10-section design document and human supervision on each pull request, zero-downtime compatibility views.

    💰 Industrialization of social declarations ASP/DSN: annual AEI subsidy of several million euros secured for a regional scope, 18,000 hours of declaration errors avoided per month since February 2026 (~€54,000/month of subsidy secured on this lever alone), 656 daily manual clicks eliminated by a centralized multi-account Python script.

In April 2026 alone: 25,000 lines of code delivered (~20% of the mission's total LOC in ~5% of the time), 3 structural projects in parallel.
