Hello!

We are a team that has been developing bots for over five years. Our main tools are NodeJS and Python. We also work with any databases (MongoDB, SQL, Postgres, etc.), integration with payment systems, API services, and plugins.

We would like to discuss the details of your project, after which we can agree on a comfortable price and convenient deadlines for both parties. After the development is completed, we guarantee to provide technical support and consultations for 10 days.

You can find examples of already implemented and working products on our website - https://vaysed.me/ or in the freelance profile.

We look forward to your response!

Hello.
I will create a "bot + pool of workers" system in Python: an interface bot on aiogram 3 with whitelist access and a backend on Telethon/Pyrogram, which processes checks through a set of MTProto sessions. Account rotation will be circular, with a strict binding of proxies to each session (ip:port:login:pass), and in case of FloodWait, the worker automatically goes on pause and the task is transferred to the next live account. If the session is revoked/banned, we mark it as Dead and send an alert to the admin so you can quickly replace the account.

Hello! 👋

I clearly understand your task: a system with a bot interface and a pool of user bots that checks numbers for registration in Telegram, bypassing limits through account rotation, proxies, and proper handling of FloodWait.

What I can do according to your specifications 💻
• 🧩 Frontend + Backend architecture
• A bot on aiogram 3 with whitelist access by Telegram ID.
• A separate "engine" on Telethon / Pyrogram with a pool of technical accounts (.session files).
• Logic: the user sends a number / list → the task goes to a worker → the result returns to the bot.
• 🔁 Account rotation + anti-fraud
• Support for 20+ sessions.
• Round-robin: each new request is processed by the next active session.
• If an account hits FloodWait — it is temporarily excluded from rotation for X minutes.
• If the session is revoked / banned — it is marked as DEAD + an alert is sent to the admin in the tech chat.
• 🌐 Proxy for each account
• Format: ip:port:login:pass for each account.
• 1 account = 1 unique IPv4 proxy.
• Configuration through config / DB, so it can be easily changed or new ones added.
• 📞 Method for checking the number
• Adding the number as a contact → retrieving data → instant deletion of the contact.
• Bot's response:
• ✅ Registered (ID + username, if available).
• ❌ Number not found.
• 🗂 Storage and configuration
• SQLite or JSON for:
• the whitelist of users;
• the statuses of workers (alive / flood / dead);
• error logs.
• A separate config file: API_ID, API_HASH, bot token, admins, timeouts, list of sessions and proxies. Expand

Hello!
My name is Ruslan, I am a Python developer with experience in creating Telegram bots and working with MTProto (Telethon / Pyrogram).

The technical specifications are completely clear. I can implement:
a bot on Aiogram 3.x with a whitelist
a pool of 20+ sessions with round-robin rotation
a strict binding of 1 account = 1 proxy
number verification through Import/Delete Contacts
handling FloodWait (temporary exclusion) and permanent ban with alerts to the admin

All settings will be through .env, account statuses will be in SQLite/JSON.
I will provide the code, requirements.txt, and deployment instructions for Ubuntu.

Timeline: 15 days
Budget: 20,000 hryvnias

I am ready to discuss the details and start immediately. Expand

I have reviewed the technical specifications, the task is clear, and the architecture is adequate. I have done systems many times using the aiogram + Telethon/Pyrogram combination with multi-accounting, session rotation, proxies, and handling FloodWait/bans — I understand where Telegram "hits" and how to navigate this carefully without leaking accounts.

What I propose for implementation:
- Clear separation of Frontend (aiogram 3.x) and Backend (MTProto workers)
- Round-robin session rotation + exclusion of accounts during FloodWait for a specified TTL
- Strict binding of 1 session = 1 IPv4 proxy
- Checking through add/remove contact without cluttering accounts
- Worker statuses: Active / Cooldown / Dead + alert to admin
- Storing whitelist and worker states in SQLite (more reliable than JSON under load)
- All configuration moved to .env config

The result will be a ready-to-deploy tool, not a "quick script": code, requirements, clear instructions, assistance with initial launch, and further support as agreed.

If needed, I can offer a simplified version for a smaller budget or, conversely, a scalable option for increased load. Expand
