Web3 Developer
Backend developer with strong experience in Java, Kotlin, and Web3 technologies. I've built smart contract integrations (Solidity, Anchor), token presales, DeFi logic, and NFT systems across EVM chains, Solana, and Sui. On the backend, I work with Spring Boot, clean architecture (Hexagonal, CQRS), and have shipped production-ready Web3 platforms and Telegram-integrated dApps.
I’m looking for a backend role in a Web3 team where I can contribute to real products — whether that’s dApps, infrastructure, or developer tools.
