About me
Your clients message you at 11 PM — and by morning they've already bought from a competitor. A Telegram bot fixes that. I build bots that: ✔ Reply instantly, 24/7 ✔ Take bookings and orders automatically ✔ Answer FAQs with AI (Claude / GPT) ✔ Send every lead straight to your Telegram or CRM You get: full setup, hosting guidance, source code, and a video walkthrough of how everything works.
