About Gilles

Senior IT Consultant with 15 years of long-term assignments for large accounts (Sanofi, AXA, Allianz) and hyper-growth startups — via A30 Conseil.
I orchestrate IT transformation projects that CIOs oversee but lack the resources to execute: complete structuring of IT functions, massive migrations, Microsoft Cloud deployment, sensitive information governance, immersive Digital Learning.
What sets me apart: I cover the entire chain — from budgetary and strategic framing to operational technical delivery. Strong UX culture, rigorous management of budgets and suppliers, ability to manage both business and technical stakeholders.
