I will build a telegram mini app or bot with wallet integration
Backend Engineer Telegram Mini Apps and Web3
Over deze dienst
I build Telegram Mini Apps and bots with production-grade backends.
I work on a multi-chain crypto trading platform covering Base, BSC, Solana, Monad and Robinhood Chain. I also built a Telegram Mini App and DEX on TON with bonding-curve pricing, token creation on STON.fi and DeDust, and soft wallet deposits and withdrawals.
WHAT I BUILD
Telegram bots commands, notifications, admin controls, payments
Telegram Mini Apps full web apps inside Telegram with native auth
Crypto wallet integration deposits, withdrawals, on-chain transactions
Backend APIs Node.js, NestJS, TypeScript, MongoDB, Redis
Deployment on AWS with CI/CD
WHY IT MATTERS
Most Mini App exploits come from one thing: developers who don't validate Telegram init data correctly. That's how accounts get spoofed. I handle it properly, along with secure token storage and protected payment flows.
I don't write smart contracts. I build everything around them.
HOW I WORK
Fixed scope agreed upfront. Clear deadline. Daily updates. Clean documentation and full handover. If your project isn't a good fit, I'll say so before you order.
Message me first to confirm scope and package. I usually reply within an hour.

Veelgestelde vragen
Do you write smart contracts?
No. I build the backend, APIs, wallet integrations and infrastructure around them. If you need contract development I can work alongside your contract developer.
Which blockchains do you work with?
TON, Solana, and EVM chains including Base, BSC and Ethereum. Tell me which you're using and I'll confirm fit before you order.
Can you work with my existing codebase?
Yes. Share the repo and I'll review it first, then give you a fixed scope and timeline before any work starts.
