Hello, Kateryna! 👋
My name is Semen, I am a fullstack developer with experience in creating Telegram Mini Apps, as well as integrations for cryptocurrency services (including P2P, Binance API, exchanges, payment gateways, etc.). I am ready to develop a functional, fast, and secure Mini App for a cryptocurrency exchange tailored to your business needs.
🔧 Capabilities I can implement:
Authorization via Telegram and verification
Currency exchange calculator with live rates
Support for major cryptocurrencies (BTC, ETH, USDT, TON, etc.)
Integration with the exchange or trading platform API (for example, Binance, Whitebit, CoinMarketCap)
Personal account: transaction history, statuses, support
… Messages/notifications in Telegram or email
Adaptive UX according to Telegram Web App Guidelines
Secure request processing + anti-fraud logic
📲 Technology stack:
NestJS / Node.js + PostgreSQL / MongoDB + Telegram WebApp SDK + React / Vue + Redis / Webhooks / Docker
(I also have experience with Python bots if backend for Mini App is needed)
💰 Budget:
from $1000+ — depending on functionality, API, type of integration, and role of the Mini App (showcase or full-fledged system)
🕒 Timeline:
from 10 to 20 days — we will discuss the details, I will show the first prototype quickly
📎 Examples of work / cases:
🔹 Telegram Mini App for the P2P team of Binance Institutional with subaccount support
🔹 Bot for automating the exchange via Binance API + statistics in Google Sheets
🔹 Platform for internal trading with order, client, and limit accounting
I am ready to discuss the details of your project, propose architecture, API structure, and optimal interaction scenarios. I will also assist with launch, hosting (Render / Vercel / VPS), and further support.
Contact me in a convenient way — I will respond quickly.
I would be happy to implement a powerful crypto service for you in the Telegram Mini App format 💻🚀
Best regards,
Semen | Web & Telegram developer

Hello, I have over 5 years of experience in chatbot development, and I am currently actively moving towards mini apps. So far, I have only developed 1 mini app, but this is due to the inability of clients to finance such projects!)
I would be happy to discuss your project and work together! I look forward to your message.
