Back to original languageAbout Julien
My specialty: I combine a concrete understanding of production and support service issues (methods, quality, etc.), acquired as close to the ground as possible, with development skills that allow me to design the analysis, automation, and management tools my clients need myself.
Thus, I help industrial sites reduce waste in their processes (production and support services) through a structured, analytical, and factual approach, drawing on the principles of Lean Manufacturing and continuous improvement.
