Part designation:
Role: Data Analyst · BI / Operations · Cologne, DE
I turn production, quality, and business data into decisions people can act on.
17 years of automotive engineering on Ford, GM, and Stellantis programs, retrained into data. Python, SQL, and Tableau, backed by the 8D discipline of a quality engineer.
Section A-A · Why this profile
Most analysts learn the domain from dashboards. I spent 17 years inside it: plants, suppliers, launch ramps. Then I learned the data stack.
I have stood at the line where the data is produced: plants, suppliers, launch ramps. I know what the numbers mean physically.
8D, SPC, PPAP/APQP: a root-cause discipline that transfers directly to analytics. Hypothesis, evidence, corrective action.
Years of aligning OEMs, plants, and suppliers: I explain models and metrics to non-technical stakeholders without losing the substance.
