What I'm looking for

I'm looking for a junior ML engineering role where I can build end-to-end data and ML products, develop advanced Python and analytics skills, and contribute to deployed services.

I build end-to-end ML projects, from collecting raw data and designing relational databases to deploying models as microservices.

At Yandex Crowd, I analyzed web pages, text, and images for relevance, anomalies, and spam. I prepared raw data and tested search-algorithm updates, identifying edge cases and response-generation errors for development teams.

At ANCOR, I labeled and classified datasets for ML training across e-commerce, finance, and healthcare. I also supported search-feature launches through A/B testing and structured feedback to ML teams while consistently exceeding task-volume KPIs.

I’ve built a Wildberries pricing analysis pipeline, an AI image detector deployed on Hugging Face, and a Steam indie-hit predictor with a FastAPI microservice and Telegram bot.
