Blockchain / Web3 Developer
A blockchain / Web3 developer builds decentralized applications: writing and auditing smart contracts (Solidity, Rust), designing tokenomics and DeFi protocols, and integrating blockchains into traditional products through indexers, oracles and wallets. The specialist pays particular attention to security — mistakes in contracts are irreversible and cost real money. They understand the EVM and alternative networks, gas optimization and cryptographic primitives.
