Marta C.

PT-BR/EN Linguist & UX-Savvy Copywriter

From Raw Content to Refined, Responsible & Culturally-Tuned UX. Bridging language, compliance, and creative intent to craft content that connects — clearly, safely, and with purpose. -------------------- Hi, I’m Marta — a multilingual content and operations expert with a passion for meaningful, compliant, and effective communication. I'm a Brazilian native speaker of Portuguese (PT-BR and PT-EU), fluent in English, and currently based in Northern Europe. I specialize in translation, localization, content creation, and quality assurance — especially for digital products, apps, and marketing — with a growing focus on compliance, governance, and risk-aware content operations. With over a decade of experience across translation, journalism, and customer-facing roles in international events like the FIFA World Cup, Bundesliga, and Premier League, I bring cultural sensitivity, linguistic precision, and confident communication to every project. My academic background includes degrees in Social Sciences and Journalism, plus coursework in Law. I also work in the construction and design industry as a Project Coordinator and Procurement Specialist, managing multilingual documentation, vendor compliance, stakeholder agreements, and technical content — from playgrounds to public spaces. In the tech and language sectors, I’ve collaborated on QA and localization for global apps, ensuring content is not only accurate but also compliant with industry standards and local regulations. I’m experienced in AI data annotation and linguistic validation, and increasingly involved in projects related to Responsible AI, risk management, and asset documentation workflows. I love bridging cultures and helping brands truly “speak” to their audiences — responsibly, clearly, and with purpose. 🔧 What I bring to your project: ✅ Translation (PT-BR, PT-PT, EN) ✅ Localization (UX, websites, apps, digital platforms) ✅ SEO-optimized content writing & editing ✅ QA & linguistic testing (mobile apps, UI/UX) ✅ AI training & data annotation (PT-BR, NLP-focused) ✅ Technical writing (manuals, product specs) ✅ Marketing & social media copy ✅ Ghostwriting & brand voice development ✅ Voiceover (PT-BR, female tone) And yes — I come with a track record of happy clients and glowing referrals.
