About Natalia
I help businesses, agencies and content teams transform translated and AI-generated content into natural, accurate and culturally appropriate language.
I specialize in multilingual proofreading, localization QA and AI translation post-editing (MTPE) for Spanish, French and Brazilian Portuguese.
I work with websites, mobile apps, drama series subtitles, marketing content and digital products, focusing on natural dialogue, consistency, tone and cultural accuracy.
My services include:
• Localization QA
• Proofreading & Editing
• AI Translation Post-Editing (MTPE)
• App & Website Localization
• Subtitle Proofreading & Audiovisual QA
• UX/UI Content Review
• Marketing Content Adaptation
• Terminology & Consistency Checks
My background in Human Nutrition and Dietetics has shaped the way I work: methodical, detail-oriented and precise. Whether I'm reviewing subtitles, localizing an app or proofreading AI-generated content, I combine linguistic accuracy with a strong quality assurance mindset.
About my languages:
I'm a native Brazilian Portuguese speaker with over 17 years of experience living and working in Madrid and Barcelona, where I'm currently based. Over time, Spanish has become a true second mother tongue. I also run my own health and wellness website, Mas Que Manzanas, where I regularly write, edit and publish content in Spanish.
I spent 8 years in Paris while studying and working as a sound engineering assistant. That's where my French took root, and I've continued using it professionally ever since through translation, localization and multilingual content projects.
This multilingual background helps me understand not only the language itself, but also the cultural nuances that make content feel natural to native audiences.
If you need content that sounds genuinely natural in Spanish, French or Brazilian Portuguese, I'd be happy to help.
