Martin Magdinier, during the last six years, has been heavily engaged with startup and open data communities in France, Vietnam, and Canada. Through his recent projects (TTCPass and Objectif Neige) and consulting positions, he became intimate with data massage techniques. Coming from a business approach, his focus is on data management and transformation tools that empower the business user. In 2011, he started to blog tips and tutorials on OpenRefine to help other business users to make the most out of this tool. In 2012, when Google released the software to the community, he helped to structure the new organization. Today, he continues to actively support the OpenRefine user base and advocates its usage in various communities.
