Telegram bot for managing deposits of OnlyFans models
Python
Developed a Telegram bot in Python using the aiogram library for automating the accounting of deposits for OnlyFans models. The bot allows users to add deposits (including split ones), view daily and monthly totals, obtain statistics on models, and rank performers. For administrators, I implemented deposit management functions (deletion, viewing statistics) and updating the overall daily total in the channel. I used MongoDB for data storage, implemented error handling and logging. The bot supports an interactive interface with buttons and commands, ensuring convenience and functionality for the team.
Technologies: Python, aiogram, MongoDB, Telegram API, logging, pytz.
… Features:
Deposit management (addition, deletion, splitting).
Automatic updating of the daily total in the channel.
Statistics and ranking of performers.
User roles (admin/regular user).
Error handling and action logging.
