About Yohann

🚀 Is your IT, Data, or AI program going off the rails? I'll get it back on track. And I deliver.

Independent Program Manager and Delivery Manager for 15 years, I intervene on complex programs when things get stuck: scope creep, misaligned teams, jeopardized client commitment, Data or AI product stuck in POC for too long.
My role is not to audit. It's to take back the helm, deliver what was promised, and leave a team capable of sustaining it without me.

🎯 WHAT I DO
I work in 3 steps: a no-nonsense diagnosis in a few days (not an 80-slide PowerPoint, but a shared assessment involving IT, business, and teams), a concrete recovery plan with measurable results as quickly as possible, and then sustainable structuring to properly hand over (governance, rituals, tooling, skill development).
When I leave, it holds.

📈 WHAT I DELIVERED
✅ Bouygues Telecom: 3 AI products put into production (from POC to production), 500 automated PowerBI reports, management of hybrid Data / Product teams.
✅ Kering: 60+ projects managed in 4 years, multi-luxury brands, SAP/JDA scope and digital retail.
✅ BeYs: Transformation program over €10M and 50+ FTEs back on track, complete delivery structuring.

🧭 WHY IT WORKS
✅ Application IT and Data & AI in the same profile: I manage an SAP AMS in the morning and an industrialization of models the next day. A rare profile on the freelance market.
✅ Developer background: I speak the tech teams' language on their level. I can challenge estimates, architecture, tool choices. Not just "the link person".
✅ I arrive, I diagnose, I decide. No consultant posture of observation.
