Katarzyna K.

I’m a native Polish Language Expert and AI Linguist with 20+ years of professional experience in translation, localization, linguistic evaluation, editing, and language instruction. I hold a Master’s degree in Philology from the University of Warsaw, with a strong academic background in Applied Linguistics and Slavic languages. My work goes beyond literal translation. I specialize in determining whether Polish content is not only grammatically correct, but also natural, culturally appropriate, consistent, and written the way a native Polish speaker would actually express it. MY CORE EXPERTISE • AI & LLM Language Evaluation • AI-Generated Content Review & Refinement • English → Polish Translation & Localization • Machine Translation Post-Editing (MTPE) • Linguistic QA & Quality Evaluation • Editing, Proofreading & Rewriting • Localization & Cultural Adaptation • Transcreation & Creative Translation • Literary Translation • Subtitling & Transcription I have professional experience evaluating machine-generated and translated content for accuracy, fluency, naturalness, context, terminology, and cultural relevance. I have also worked on time-sensitive linguistic evaluation projects where consistency, attention to detail, and reliable language judgment are essential. Alongside my linguistic work, I have many years of experience teaching Polish to international students and working with clients from different linguistic and cultural backgrounds. This gives me an additional perspective on how Polish is actually understood and used. I am also a published author and literary translator with bilingual publications, giving me extensive experience preserving voice, emotion, style, and meaning when literal translation simply does not work.

If you need someone who can recognize the difference between Polish that is technically correct and Polish that actually sounds Polish, I can help. Accurate. Natural. Culturally aware. Human.
