I worked with Valentin on a data mission within our DMO. He distinguished himself by his rigor, his sense of service, and his ability to provide concrete solutions quickly. Valentin structures, documents, and transmits: his pragmatic approach and clear communication facilitated collaboration with business and tech teams. Beyond his technical skills, he is autonomous, proactive, and always reliable in his commitments. I highly recommend him for any data mission requiring efficiency, pedagogy, and teamwork.
