I’m a professional writer, translator, proofreader, and data annotation specialist with 9 years of hands-on experience delivering high-quality language and content solutions.

As a translator and proofreader, I’ve worked on full website localizations as well as detailed content refinement, ensuring linguistic accuracy, natural flow, and consistency with brand voice. I go beyond literal translation — adapting content to cultural context, user intent, and SEO requirements. I also have experience in data annotation and AI-related projects, including content labeling, evaluation, and optimization workflows. This allows me to support machine learning processes with precision, consistency, and attention to detail. My background includes specialization in iGaming and IT, where I’ve collaborated with well-known brands and delivered content aligned with industry regulations, user expectations, and technical accuracy. In addition, I’ve worked across a wide range of industries, including automotive, lifestyle, nutrition, legal, medical, education, and other popular content verticals. With 6 years of formal IT education and practical experience in technology, cybersecurity, and digital systems, I’m especially comfortable handling technically complex or highly regulated topics. What I bring to your project: ✔ Writing, translation & proofreading – clear, natural, and high-quality content ✔ Data annotation & AI support – labeling, evaluation, and content optimization ✔ SEO expertise – search intent, on-page optimization, and content structure ✔ Industry versatility – iGaming, IT, automotive, lifestyle, nutrition, legal, medical, education & more ✔ Strong research skills across complex and technical topics ✔ Experience with SEO tools (Ahrefs, AccuRanker) ✔ Consistent quality at scale ✔ Clear communication & reliable deadlines I focus on delivering content that builds authority, trust, and real results — not generic text.
