7-day intensive on data work within Telegram.
Monthly active users
Data Marathon is a 7-day intensive focused on working with data directly inside Telegram, led by Nikolay Valiotti (@leftjoin). The bot acts as a structured entry point to the course content and related information.
Using /program, users can view the full curriculum and see what is covered each day of the intensive. This helps to understand the scope of topics and plan learning time.
The /tutor command provides details about the instructor and his background in data and Telegram tooling. The /questions section aggregates frequently asked questions about the format, content, and organization of the intensive.
With /contacts, the bot shares contact information for follow-up and organizational issues. All navigation is based on simple commands, so participants can access essential course information without leaving Telegram.
Data Marathon targets users who want to deepen their skills in data operations within the Telegram ecosystem, including analysts, developers, and product specialists working with bots and mini apps.
