Marina A.

Medical & Technical EN PT Translator | Proofreader | Voice Over Artist

Top Rated translator, proofreader, and voice over artist with 100% Job Success — because precision, reliability, and professional-grade quality are non-negotiable to me. I am Marina, a native Portuguese speaker with a Master's degree in Pharmaceutical Sciences and over 10 years of experience delivering English-to-Portuguese translations, proofreading, and voice over production across technical, medical, legal, and marketing fields. My academic background in chemistry, medicine, anatomy, biology, and nutrition gives me a decisive edge when accuracy truly matters — particularly in pharmaceutical, clinical, and scientific content. Throughout my career, I have translated and proofread websites, books, scientific articles, software, mobile apps, scripts, and online courses — always ensuring the final text reads as naturally in Portuguese as it does in the original English. Every delivery is contextually precise, orthographically flawless, and 100% human. As a professional Voice Over Artist, I have recorded and synchronized over 1,000 hours of video and audio content. I work from a fully equipped home studio with professional-grade audio software for editing, improvement, and mastering — so you receive broadcast-ready files from day one. What sets me apart: I treat every deadline as a commitment, not an estimate. If I agree to a timeline, I deliver — without cutting corners on quality. My clients return not just because I translate words, but because I translate meaning. Ready to get started? Let's talk about your project.
