About
What I Do
I help organizations define what "quality" actually means — then measure against it.Why I Do It
Designing evaluation frameworks and auditing German-English content isn't just what I do — it's what I genuinely love. There's something deeply satisfying about turning something as subjective as "quality" into a clear, defensible standard anyone can apply consistently. It's where native-level linguistic precision meets structured, rubric-based methodology.My Background
Native German (C2), Master's in eLearning and Education, Goethe-Institut DaF certification, Quality Matters certified, and EU-certified Master-level Cross-Cultural Communication. Applied this work with Google (via GlobalLogic), Microsoft (Blueprint), and Rosetta Stone/IXL.

Evaluation Framework Design
Every quality judgment should trace to a specific dimension, weight, and piece of evidence — not just a gut feeling. I design custom weighted rubrics with disqualifier criteria for critical failures, so any reviewer's judgment holds up under scrutiny — for AI content, translations, or training data alike.Localization QA
A technically accurate translation can still fail if the tone is off or terminology drifts. I audit German-English content for terminology consistency, register, and cultural fit — catching what a standard translation pass misses.Content Quality Standards
Inconsistent quality is usually a standards problem, not a talent one. I help teams build clear terminology guides and review protocols, so quality checks stop depending on who happens to be reviewing — and start being repeatable.
