Executive summary

Head of Product — RegTech · FinTech · SocialTech — operating where systems become partially unreadable.

More than 20 years designing, leading, and scaling complex digital products. I combine product vision, operational excellence, strong run ownership, and a culture of proof in high-constraint environments: fraud, security, sensitive data, and multi-stakeholder organizations.

My differentiating angle: connecting architecture, usage, compliance, weak signals, and decision-making. A rare level of systems depth while remaining focused on outcomes, adoption, robustness, and business impact.

A profile built for situations where systems become blurry, costly, or difficult to evolve.

My role is not just to lead a product. I step in where a system becomes partially unreadable, underused, or difficult to evolve.

// Statement of intent § 2026
01 Step 01

I clarify.

I make unclear areas readable: architecture, governance, usage, weak signals, and priorities.

02 Step 02

I transform.

I modernize systems, reactivate the tools that matter, create the right adoption levers, and structure execution.

03 Step 03

I reposition.

I reconnect the product to market value, potential customers, and a credible growth logic.

Measured expertise.

Detailed case file — AlloCestMoi

Switch invisible in product.

AlloCestMoi starts from difficult material: audio, the fear of speaking up, legal sensitivity, workplace violence, and anonymity. The product role was to make that material readable, manageable, and usable without betraying trust.

// 45 dots = 45 countries crossed · 2018–2021 · Field observation

45 countries in 3 years.

// Field case — autonomy & adaptation

A long field experience in unstable and loosely structured environments. Each dot on the map represents a situation handled without a pre-existing framework: visas, logistics, cultural negotiation, and rapid reading of human systems.

What it demonstrates: a rare ability to operate sustainably in heterogeneous environments — and then turn that experience into structured, actionable insight for decision-making.
