Back to original languageAbout Nathan
Are you looking for an Excel trainer who knows the field? Or a developer who can teach?
I'm Nathan, an independent Excel engineer and 2-time Microsoft MVP.
For over 10 years, I've been designing custom Excel tools for large corporations (LVMH, L’Oréal, Total Energies, Renault, GRTgaz, Liebherr…) and training the teams that use them.
🎓 PROFESSIONAL TRAINING (registered organization - active NDA)
I offer company training programs lasting 1 to 5 days, in-person or remote:
· Advanced Excel (modern formulas, tables, PivotTables, Dashboards...)
· Power Query & M language (import, transformation, ETL automation...)
· Power Pivot & DAX (relational modeling, measures, dashboards...)
· VBA (automation, business tool development, userforms...)
➤ Over 1,500 learners trained; employees, managers, analysts, IT teams
➤ Hands-on pedagogy; I train on the tools I build daily
⚙️ DEVELOPMENT & AUTOMATION
I design custom and 100% automated Excel tools:
· Dynamic dashboards and automated reporting
· Multi-source data consolidation via Power Query
· Custom VBA business applications (data entry, control, export, Gantt...)
· Optimization of existing files (performance, reliability, usability)
Example: automation of a financial file for a major gas group - execution time reduced from 1.5 hours to 4 minutes.
💬 Let's discuss your project - training, development, or both. I respond within 24 hours.
