Improve the existing Telegram Bot project

Project Brief:

An experienced developer is required to refine and fix bugs in an existing Telegram bot written in Python. The bot is designed for buying and selling traffic (subscribers) and has three user roles: Client, Supplier, and Admin. The main functionality has already been implemented, but there are errors in the code, and some functions may be incomplete. The goal is to completely fix all shortcomings and bring the project to a state where it fully complies with the original technical specifications (which will be provided to the contractor).

What Needs to Be Done

• Analysis and Bug Fixing:

  • Examine the existing code, identify and fix all logical and technical errors that lead to failures or incorrect operation.

• Completion of Functionality:

  • Check all functions described in the technical specifications and refine those that have not been fully implemented or are working incorrectly. This includes:

    • Traffic Purchase Process: Ensure that all stages of order placement work without failures (selecting the number of subscribers, setting filters, checking balance, sending the order to the admin).

    • Interaction with Suppliers: Check and establish the process of connecting supplier bots, as well as the automatic distribution of orders among them.

    • Admin Panel: Check the functionality of all administrative functions, including order confirmation, user balance management, and viewing statistics.

    • Payment System: Set up balance replenishment through CryptoBot and other cryptocurrencies.

Requirements for the Contractor

• Experience: Experience with Python and the aiogram library is mandatory.

• Database: SQLAlchemy, Alembic (for migrations).

• Working with APIs: Aiohttp, Requests.

• Asynchronous Operations: Asyncio, aiosqlite.

• State Management: Redis (for storing user states).

• Debugging Skills: Ability to quickly find and fix errors in someone else's code.

• Communication: Willingness to discuss and agree on alternative solutions if difficulties arise during implementation. I am ready to compromise or simplify the task if necessary.

• Deadlines: Priority is given to speed of execution and full functionality of all features.
