I specialize in Polish localization QA and UX-focused language review for mobile apps, websites, onboarding flows, fintech, SaaS, and digital products. I also provide web and desk research, fact-checking, source verification, and keyword research.
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 also support research-based projects, including:
• web and desk research across Polish- and English-language sources
• fact-checking and source verification
• company, product, competitor, and industry research
• keyword and search-intent research
• collecting, comparing, and organizing information from multiple sources
• research support for articles, reports, websites, and content projects
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, including web and mobile apps
• website localization and adaptation for Oazis Car from Russian and English into Polish
• proofreading and localization QA for Skycop
I pay close attention to detail, usability, source quality, and tone consistency. Whether I am reviewing a localized product or researching a topic, my goal is to deliver clear, reliable, and well-structured results.
