About Jérôme

Delivery in difficulty?
Lack of product clarity or misalignment between teams?
I step in as an interim CTO to regain control and relaunch.

What I do

I support technical organizations facing:
• Unstable or unpredictable delivery
• Product / engineering / business misalignment
• Organizations that no longer scale
• Blocking technical or organizational complexity

How I intervene
• Taking back control of delivery
• Clarifying product priorities
• Structuring teams and responsibilities
• Reducing complexity
• Aligning stakeholders

Proof (Malt key)
• Delivery out of control → returned to 40% delay in 6 months
• Unstable organization → stabilization after critical turnover
• Programs managed up to 100+ people / 7 sites

Typical missions
• Interim CTO (3–9 months)
• Taking over a struggling team
• Delivery recovery
• Critical program management
