What I'm looking for

I’m looking for remote contract or full-time work where I can help train and evaluate LLMs, improve prompt quality, and deliver high-quality Russian/EN content—ideally in a fast, ambiguous, AI-native environment that rewards hands-on iteration.

I’m a linguistics graduate with a daily, hands-on relationship with modern LLMs—ChatGPT, Claude, Cursor, OpenAI Codex, Grok, DeepSeek—and I use them to ship real outcomes, not just demos. I direct AI tooling end-to-end: from product idea and UX to working prototypes, automations, and bilingual content.

In my current role, I do AI data annotation and LLM response evaluation: I review, compare, and improve model outputs in English and Russian against project guidelines. I focus on structured quality feedback—accuracy, clarity, tone, and instruction following—so the results are dependable for training and deployment.

Alongside evaluation work, I build AI-assisted products and operational workflows, including custom GPT-powered Telegram bots and end-to-end Telegram channel automation. With an applied linguistics foundation and an operator mindset, I’m seeking remote contract or full-time roles in AI training, Russian copyediting, LLM evaluation, prompt engineering, or AI-native content operations.
