With 15 years of experience in critical systems at Alstom, SNCF Réseau, and Systra, I support business and IT departments in steering their performance through data. My hybrid profile allows me to understand your technical field challenges while translating them into automated and scalable Data solutions.
What I bring to your projects:
Data Analysis & Decision-Making Visualization: Design of complex dashboards in Power BI (DAX, Power Fx) and automated reporting to transform your raw data into real-time steering tools.
High-Stakes Project Governance: Expert in managing large departments (up to 100 people), I ensure mastery of QCD (Quality, Costs, Deadlines) and risk management on critical scopes.
Railway Business Expertise: In-depth knowledge of signaling systems (ERTMS/ETCS, PAI, SEI) and design/execution phases (AVP, PRO, REA).
Innovation & AI: Deployment of automation workflows (n8n, Python) and integration of AI agents to optimize your internal processes and reduce low-value-added tasks.
Key Achievements:
SNCF: Industrialization of performance reporting for the Customer and Territory Directorate using Power BI, VBA, and Python.
Alstom: Performance steering for a department of 100 people and reduction of delivery times on ETCS/ERTMS projects (gain of several days per deliverable).
Automation: Implementation of secure local AI infrastructures (Docker, LM Studio) for automating business workflows.
Why collaborate together?
My approach is that of an operational partner: I don't just deliver a tool, I secure your objectives and ensure the upskilling of your teams through fluid and structured communication.
