Over mij
I build crypto exchange websites, P2P platforms, and wallet apps with real smart contract integration, not just template reskins. My work covers admin panel development, wallet connectivity (MetaMask, WalletConnect), custom token logic (ERC-20/BEP-20), and secure backend architecture for exchange platforms. Whether you need a fast MVP to launch quickly or a fully custom build with KYC, multi-currency support, and live trading logic, I deliver clean, working code, not just a pretty front end.
