About Cristina

Twenty years. Twenty-five countries. Always the same moment: someone entrusts me with a situation that is too complex, too urgent, or too fragile to function normally — and asks me to make it work.

I AM AN INTERNATIONAL HR LEADER IN TRANSFORMATION — TRANSITION MISSIONS, EMEA SCOPE. I INTERVENE IN FOUR TYPES OF MISSIONS:

• M&A PMI — from HR due diligence to post-merger stabilization, including Day 1 preparation.

• HR TRANSFORMATION — redesign of the operating model | GBS | Shared Service Centers, HRIS implementation (Workday), process optimization.

• RESTRUCTURING — workforce planning, change governance, operational continuity.

• PMO — program governance, roadmap ownership, executive reporting.

Comfortable in a wide variety of sectors, geographies, company sizes, and HR disciplines — which allows me to adapt quickly and be operational immediately.

Where I go in-depth is where transformation is non-negotiable: M&A integration, restructuring, hypergrowth, and making HR technology truly serve people.

What I bring is atypical: I can hold the strategic framework AND dive into the operational layer. I don't hand over when things get complicated — that's usually where I start.
