Backend Developer at Yandex Crowd

Yandex Crowd is a large infrastructure service of Yandex. We implement crowdsourcing to scale business processes (data labeling, content moderation, field research, testing) and build internal product features (customer service, telemarketing, localization, and documentation).

We launched the crowdsourcing platform Yandex Tasks, participated in the launch of YandeхGPT, the launch of Search in Kazakhstan, teaching Alice Arabic and even whispering, and many other Yandex projects.

We are currently implementing projects aimed at improving the lives of our users, as well as deploying AI agents, creating frameworks for building flexible data processing pipelines using the capabilities of Human and Artificial Intelligence, and doing much more. Some projects are developed as completely new services, while others are based on existing solutions.
