About this gig

I build modern Telegram Mini Apps that run inside Telegram and connect to your bot and backend.


Good for:

- SaaS products and customer dashboards

- Subscription services

- Booking and appointment systems

- E-commerce and catalogues

- Loyalty and referral programs

- Internal business tools

- Community products


What I deliver:

- React based Telegram Mini App

- Secure Telegram authentication with server-side initData validation

- Node.js and TypeScript backend

- PostgreSQL or MongoDB database

- Telegram Bot API integration

- Telegram Stars payments

- External API integrations

- Responsive UI that follows the Telegram theme

- Deployment and production setup

- Full source code


Telegram authentication is only safe when initData is validated on the server. I implement this

properly on every project a Mini App that trusts the client can be spoofed by anyone.
