What I'm looking for

I seek roles where I lead localization and UX writing efforts, collaborate cross-functionally, and drive measurable improvements in product usability and cultural relevance.

I am a Localization Lead, translator and UX writer with extensive experience crafting culturally sensitive user experiences for global audiences. I combine Russian linguistics, copywriting and localization management to deliver accurate UI text, glossaries, and LQA processes that improve engagement and product usability.

I've trained AI language models, led localization projects end-to-end, and driven measurable improvements—boosting model accuracy, reducing localization errors, and increasing conversion and brand visibility through targeted copy and strategy. I collaborate cross-functionally, optimize workflows, and prioritize user-centered, high-quality localized content.
