What I'm looking for

I'm open to product, data, and AI/ML engineering roles, and to remote, hybrid, or on-site work. I'm also open to relocation.

At Yandex, I developed and maintained the core backend for Ya.Smena, a high-traffic workforce platform used across Yandex services. I built account linking to reduce fraud and migrated production data without downtime.

I also delivered a partner recommendation system that improved user retention by 10%, and built in-platform chat that increased user activity by 15%. At Innostage, I built an Apache Airflow plugin for designing pipelines through a UI and developed a Python package for processing log flows from UDP and RabbitMQ servers.
