Miguel S.

English & German → Spanish & Catalan Translator | Localization | Proofreading | AI Post-Editing I am a native Spanish (Spain) and Catalan linguist with over 20 years of professional experience in translation, proofreading, localization, and linguistic quality assurance (LQA). Since 2004, I have helped agencies, publishers, and international companies deliver accurate, natural, and culturally appropriate content for Spanish-speaking audiences. My expertise covers technical, automotive, IT, software, marketing, tourism, sports, music, education, website localization, and e-commerce, as well as AI-generated content review and machine translation post-editing (MTPE). My goal is always to deliver translations that sound native and are ready for publication. In recent years, I have also worked on AI evaluation and post-editing projects, reviewing machine-generated translations, assessing linguistic quality, and improving AI output for publication. In 2024, I collaborated on Microsoft Copilot AI evaluation and prompt assessment, gaining hands-on experience with Large Language Models (LLMs) and AI-generated content workflows. Besides translation, I have extensive experience in proofreading, editing, linguistic QA (LQA), terminology management, subtitle translation, transcription, and localization testing. I have transcribed more than 400 hours of audio and video in Spanish and Catalan and regularly review websites, software, and AI-generated content.
