About

Professional summary

I am a German native-language post-editor, quality reviewer, and AI language data specialist working across English, German, Italian, and Spanish.

Since 2023, I have focused on improving and evaluating machine translation and LLM output through light and full post-editing, MQM-based quality evaluation, response rating, prompt writing, and linguistic asset development.

I bring hands-on experience with MTPE, LQA scorecards, engine evaluation, adversarial prompting, terminology management, locale style guides, and in-context UI review. I use risk-based triage to balance delivery speed, quality, and content risk.

Across my recent roles, I have post-edited or evaluated more than 450,000 words, maintained an average LQA score of 97/100, and helped reduce turnaround time for MT-suitable content by approximately 35%.

My earlier experience as a Senior Web Architect gives me a practical technical foundation in JSON, XML, REST APIs, and automated workflows. I work effectively as a bridge between linguistic, product, and engineering teams.

Career history

Senior Associate Elite Language Craft

I post-edit and review machine translation and LLM output across English-to-German, Italian, and Spanish language pairs. Since February 2025, I have post-edited approximately 180,000 words while maintaining an average LQA score of 97/100.

I introduced risk-based triage for light versus full post-editing, reducing delivery time for suitable jobs from three days to under two without increasing error rates. I designed an MQM scorecard used on every project, helping account quality scores improve from 93 to 97 over three quarters.

I also evaluate MT and LLM engines for new accounts, with recommendations adopted on five of six reviewed accounts. My work includes rating and rewriting German and Italian LLM responses against client rubrics and creating adversarial prompts to test safety and factual accuracy.

Freelance Translator & Localization Specialist LinguaVox

I post-edited approximately 45,000 words of machine-translated UI and help-centre content. My work improved translation-memory leverage on repeat releases to above 60% while maintaining 98% client satisfaction within a 100,000-word delivery scope.

I reviewed AI-generated product descriptions for Italian launches and identified 32 critical issues, including invented features and incorrect units, during one release cycle. I also established in-context review for UI projects, reducing post-release linguistic bug reports by approximately 60%.

Freelance Translator & Localization Consultant Polyglot Labs

I translated and post-edited 100,000 words of web, application, and knowledge-base content for digital-first brands.

I developed locale style guides that were later reused as prompt instructions for AI-assisted content. I also streamlined workflows using CAT tools and machine-translation pre-translation, reducing time to market by approximately 30%.

Senior Web Architect Novanet Solutions

I led the architecture of web platforms for finance and e-commerce SMEs, working daily with JSON, REST APIs, and automated pipelines.

This technical background provided experience with the building blocks now used in machine translation and LLM data workflows, enabling effective collaboration between language and engineering teams.
