About the service

I build mini-apps for Telegram — full-fledged web interfaces that open right in the chat via a button under the bot, without switching to a third-party site and without installing a separate app. If you have a store, service business or practice with client booking, I turn your product catalog, price list or schedule into a convenient interface that users reach with a single tap.

The work includes the full cycle: interface design in the messenger's own style, web app development, data storage and integration with your existing bot logic so orders, bookings and payments flow to one place. I pay special attention to loading speed and correct operation on both phone and desktop client — a slow or inconvenient mini-app loses clients faster than a regular website.

What I typically do in such projects:
— product catalog with categories, search and cart
— service booking with calendar and time slots
— order placement and payment via built-in payments or external gateway
— simple admin panel for managing items, prices and bookings
— transfer of key functions from an existing website to mini-app format

I also help with solution selection: sometimes a simple bot scenario is enough, while a mini-app is justified with large catalogs or complex booking.
