Telegram Chatbot Setup for Voucher Validation

I'm seeking a seasoned developer to set up a Telegram chatbot. This bot will validate voucher codes provided by my custom-built website.

Key Requirements:
- Proficiency in Python, as my website is built on this language.
- Extensive experience with Telegram bot development.
- Capability to integrate the bot with my custom-built website for real-time voucher validation.
- Understanding of secure code handling and validation logic to prevent abuse.

The ideal candidate will not only ensure a smooth setup but also deliver a bot that is efficient, reliable, and secure.
