About this gig

Hi, I'm Sem. I build Telegram Mini Apps for businesses 

the kind that turn your Telegram bot into a full app experience 

without forcing users to install anything.


What I can build for you:

  • Mini shops & catalogs (browse products, cart, checkout in Telegram)
  • Booking & appointment apps (calendar, services, payments)
  • Mini CRMs for internal team use
  • Restaurant menus with order placement
  • Loyalty programs, referral systems, member portals
  • Internal dashboards for managers and admins


Stack: React or Next.js + TypeScript on the frontend, 

Python/Django or Node.js on the backend, PostgreSQL database. 

Telegram Web App SDK for native integration.


Integrations I work with: Telegram bot (always included), 

Telegram Stars or Stripe for payments, Google Sheets, CRM 

systems, any REST API.


What you get:

  • Clean, documented source code (yours forever)
  • Deployment on a working server
  • Full bot + Mini App connection out of the box
  • Mobile-responsive design (works on iOS, Android, desktop)
  • Free bug fixes after delivery (depending on package)


Before placing an order message me with your idea. 

I'll tell you honestly what fits which package, suggest 

the right stack, and flag any tricky parts

I build Telegram bots and mini apps for businesses — the kind that solve real problems, not just say "hello world". Before coding, I spent 12+ years in business. Built and ran a manufacturing company. Moved into software because most business tools are built by people who never ran a business. What I do: — Telegram bots: booking, notifications, support — Telegram Mini Apps: shops, catalogs, CRMs — Backend Python/Django, frontend React/Next.js — Flutter mobile apps For complex projects I work with my team — but you deal with me directly. Fast replies. Clean code. No bullshit.
