About the service

I develop full-featured web applications that open directly inside Telegram, along with a bot that launches them and guides the client. Instead of taking people away to a separate website or app store, I bring your product to where your audience already spends their day. The Mini App opens instantly with a button, recognizes the user through Telegram login, and works equally well on phone, tablet, and desktop clients. Around the application I write bot logic: it greets the client, sends confirmations and reminders, handles support requests, and continues the conversation after the first order.

I handle the parts that actually make the business work, not just a pretty screen. I build product and service catalogs with search and filters, a shopping cart and clear order checkout, table or slot booking with a live calendar, and payments through Telegram's built-in payment layer or your preferred provider. Every order goes into an admin panel where your team sees requests, changes statuses, edits the catalog, and exports data. If you already have a CRM, accounting system, warehouse, or delivery service, I connect the app to them via API and webhooks so nothing needs to be entered manually.

I lead the project from a short brief to a working release: architecture, interface, bot, backend, testing on real devices, and launch with monitoring. I write clean and documented code, hand over all access, and explain how everything works so your team stays in control of the solution. After launch, I stay available for fixes, new features, and scaling as your load grows. If you want to be with clients where they already communicate and turn quick messages into real orders, a Telegram Mini App is one of the most direct ways to do it.
