The Story
Why the last 10% matters
AI translation tools have changed everything. DeepL, ChatGPT, Google Translate — they're fast, cheap, and often surprisingly good. But "surprisingly good" isn't good enough when your legal contract, medical documentation, or compliance materials need to be flawless.
Since 1994, I've worked at the intersection of languages — trained in Modern Languages at the University of Leeds and Lettres Modernes at Université Toulouse-Jean Jaurès. Today, that experience has a new application: I take AI-translated content and elevate it to professional standard. I catch the errors machines miss, fix the awkward phrasing that screams "translated," and ensure your content meets the exacting standards your industry demands.
AI gets you 90% of the way. I deliver the critical 10% where lawsuits, compliance failures, and reputational damage live.
I specialise in high-stakes industries: legal, medical, pharmaceutical, financial, and technical documentation. These are fields where "close enough" can mean regulatory rejection, patient harm, or legal liability. My clients understand that the cost of professional editing is far less than the cost of getting it wrong.
Based in Portugal, fluent in French, German, and Portuguese, I work with European companies who need their English content to be not just correct, but impeccable.

AI Translation Editing
Machine translation produces fast results. I transform them into polished, professional content that reads naturally and communicates effectively.
AI tools are impressive, but they often miss nuance, context, and the subtle choices that make writing truly effective. I bridge that gap — taking machine-translated content and refining it until it reads as if written by a native speaker.

Frequently Asked
Machine Translation Post-Editing (MTPE) is the process of refining AI-generated translations to professional quality. Tools like DeepL and ChatGPT produce output that's often 90% correct, but that remaining 10% is where legal liability, compliance failures, and reputational damage hide. I take machine-translated content and transform it into text that reads as if written by a native speaker.
AI excels at pattern matching but struggles with context, nuance, and domain-specific precision. In legal contracts, 'shall' vs 'will' can change enforceability. In medical documentation, 'contraindicated' vs 'not recommended' has regulatory implications. In technical manuals, ambiguous instructions create safety risks. The 2-8% accuracy gap in AI translation is precisely where expensive mistakes occur.
Any industry where precision matters more than speed: Legal (contracts, patents, compliance documents), Medical & Pharmaceutical (patient information, clinical trials, regulatory submissions), Financial Services (reports, disclosures, client communications), and Technical Documentation (manuals, safety instructions, specifications). When a mistranslated word can trigger a lawsuit, regulatory rejection, or safety incident, the cost of human editing is minimal compared to the cost of errors.
I edit AI translations from Portuguese, German, French, and Spanish into English. As a native English speaker with 30+ years of fluency in these source languages, I catch errors that AI makes consistently: false cognates, register shifts, cultural assumptions, and technical terminology that looks correct but isn't.
AI translation editing is faster than full translation — typically 2-3x faster for standard business content. A 3,000-word document usually takes 1-2 working days. Complex legal or medical content may require additional time for terminology verification. However, the value proposition is quality, not speed — content that protects your reputation and meets professional standards.
