I specialize in Polish localization QA for mobile apps, websites, onboarding flows, fintech, SaaS, and digital products. My work goes beyond translation and proofreading. I focus on making products feel natural, intuitive, and fully localized for Polish users. I review how language works inside the product itself, including: • linguistic QA and natural Polish UX flow • terminology consistency across screens and features • mobile app UI review and text truncation • onboarding and navigation flow validation • UX-focused localization and microcopy optimization • identifying unclear, misleading, or overly literal translations • cross-screen consistency and product logic • structured QA reporting with paths, severity levels, and correction proposals I have experience working on large-scale localization QA projects for websites and mobile applications, including fintech, crypto, SaaS, and multilingual digital products. Recent projects include: • localization QA for a large crypto platform (web + mobile app) • website localization and adaptation for Oazis Car (RU/EN → PL) • proofreading and localization QA for Skycop I pay close attention to detail, usability, and tone consistency, making sure the final product feels natural to Polish users, not translated.
