I build Telegram bots and Mini Apps that sell, take payments and run on their own. Typical scope: a shop in the chat (catalogue, cart, order status), checkout with Telegram Stars, cards or USDT, automatic delivery of the product after payment, an admin panel for you, a partner or referral programme with payouts, reminders to people who left without paying, and an AI assistant that answers questions and hands over to you when it should. Proof: NeoSIM is our own live shop: a Telegram bot plus a Mini App with card and crypto checkout, the eSIM QR delivered in the chat about a minute after payment, partner programme, and support hand-over in 10 languages. You get the source code, a deployed bot on your server or mine, a short guide for your team, and a test of the whole payment flow with refunds and duplicate callbacks. Tell me what you sell and how you want to be paid, and I will quote a fixed price and a delivery date.
