Experience connecting product, engineering, and organization

For nearly 20 years, I have worked across engineering, product, entrepreneurship, management, and transformation. The contexts change, but the same questions keep returning: what should be built, how should decisions be made, how should teams be organized, and how can sustainable execution capacity be preserved?

I have worked as cofounder, salaried CTO / CTPO, freelance leader, partner, interim manager, and coach. These roles taught me to operate both on vision and trade-offs, and on organization, leadership, and field realities.

This portfolio presents the experiences that best represent that trajectory. It complements the Case Studies page, which summarizes the types of impact created across these contexts.

Translated from French

I worked with Xavier for several months at Letmotiv. He joined a small-team context with no rituals, no stable roadmap, unsuitable tools, and a weak product culture. His support helped define a roadmap, set up weekly rituals (for example 4L retrospectives and 1:1s), equip delivery with the Atlassian/Jira suite, and track quality through DORA KPIs.
Development and deployment cycles were cut in half, communication within the technical team became smoother, decisions became faster, and it enabled a mindset shift on the product side.
As CTO, I gained calm, priority clarity, and leadership. Xavier is a demanding and kind sparring partner whom I recommend to any CTO/CTPO.

Translated from French

Xavier has supported me since June 2024 as CTO coach at Zola, during a high-growth phase in which we doubled both headcount and revenue.
His outside perspective and method helped us stay on course: clarifying the roadmap, prioritizing strategic topics, and setting up solid rituals to support this acceleration. Thanks to him, we improved quality, reduced incidents, and made collaboration with other teams smoother.
I especially appreciated his role as a sparring partner, able both to challenge and to bring concrete solutions. This support helped me grow stronger in my role, make decisions faster, and give the team more calm in a highly demanding context.
I strongly recommend Xavier to any CTO/CTPO who wants to scale successfully while gaining impact and clarity.
