Continuous Improvement Project Manager | Lean Six Sigma Green Belt Industrial Diagnostics & Transformation | I go where analysis stops | Lean Six Sigma Green Belt
Some industrial problems persist for years. Reports are written, analyses are performed—and yet nothing really changes.
With 15 years of field experience in industrial systems and 5 years in software development, I identify the root cause where traditional approaches stop—by combining in-depth technical analysis with Lean Six Sigma methodologies.
✅ 16 weeks of downtime avoided—a pragmatic solution validated with RTE. ✅ 90% of anomalies identified in 3 months after 3 years of investigation. ✅ Build time reduced by a factor of 7 after diagnosis and pipeline restructuring.
Diagnosis first, then measurable results.
Based near Grenoble.
