Hire the Best Localized Content Freelancers
in Spain

Swedish native translator, proofreader, and content writer. With expertise in English-to-Swedish translation, proofreading, copywriting, and content creation, I bring a rich and varied portfolio covering literature, applications, Amazon product listings, cryptocurrency and blockchain content, medical research, legal documents, user manuals, iGaming/casino material, technical specifications, and websites. Feel free to reach out with any questions or project inquiries—I’d be happy to help.

Most translated content has a tell. A phrase that sounds off, a rhythm that doesn't fit, a word no native would choose. I find those things — and fix them. I work with businesses, agencies and content teams who need their Spanish, French or Brazilian Portuguese to sound like it was always that way. My work covers the full localization review process: proofreading, MTPE, localization QA, website and app localization, subtitle proofreading, UX/UI content review, marketing adaptation and terminology checks. Whatever the format, the goal is the same — content that reads like it belongs. About my languages Spanish has become a native-level language after more than 17 years living and working between Madrid and Barcelona. I also run Mas Que Manzanas, a Spanish health and wellness website where I regularly create, edit and publish content. French became part of my professional and personal life during my 8 years in Paris, where I studied and worked as a sound engineering assistant. I've kept it sharp through translation, localization and multilingual content work ever since. Brazilian Portuguese is my native language. About how I work My background in Human Nutrition and Dietetics taught me to work with precision, consistency and attention to detail. Every project is reviewed manually, focusing on tone, clarity and cultural accuracy. If your content needs to sound genuinely native, let's talk.

14+ years of delivering linguistic precision for global industry leaders. As a member of the National Association of Graduates in Translation and Interpreting (CONALTI, Venezuela) (member association of the International Federation of Translators (FIT/IFT)), I bridge the communication gap between complex technical sectors and the Spanish-speaking world. My approach combines a deep architectural background with cutting-edge AI-integrated workflows to deliver translations that are not only accurate but culturally and strategically impactful. Why partner with me? I don’t just translate words; I localize experiences and secure compliance. My expertise is built on three high-stakes pillars: EdTech & Gamification: During my tenure at Duolingo and Amino Apps, I localized entire app ecosystems and curricula for millions of users, specializing in Linguistic Quality Assurance (LQA), gender-agreement audits, and cross-dialectal adaptation (Spanish MX, AR, ES, CO, VE). Fintech, Crypto & Web3: At Deriv and through Contentoo, I specialized in high-complexity trading platforms, blockchain terminology, and AML/Compliance content, achieving a consistent 100% quality score. Legal, Healthcare & Public Sector: Long-term collaborator for The Spanish Group and Baystate Interpreters, managing sensitive vital records (USCIS/Embassy standards), IEPs, and social housing documentation with strict confidentiality (HIPAA/FERPA-compliant). Technical Mastery: I leverage a robust CAT Tool stack (MemoQ, Phrase, SmartCat, Crowdin, Transifex) and Generative AI (Prompt Engineering) to optimize turnaround times while maintaining the highest stylistic integrity. Core Specialized Areas: Engineering & AEC: 11-year tenure as the lead translator for the Advanced Building Skins International Conference. iGaming & Marketing: SEO-driven localization and transcreation for B2B and B2C global campaigns. Digital Excellence: Expert-level LQA, functional bug reporting, and subtitle synchronization. Let's connect if you are looking for a proactive, tech-savvy linguist who understands that in localization, precision is the ultimate ROI.

Fully licensed and with 7+ years experience working with top-tier companies ranging from eCommerce, travelling, finance, iGaming, medicine, and many more.
