• Debug, maintain, and upgrade deployed smart contracts
• Collaborate with product and design teams to deliver end-to-end Web3 solutions

What We’re Looking For

• Strong hands-on experience with Web3 and blockchain development
• Proficiency in smart contract languages (Solidity, Rust, or similar)
• Experience with Ethereum and/or other blockchain ecosystems
• Familiarity with Web3 libraries and frameworks (ethers.js, web3.js, Hardhat, Foundry, etc.)
• Understanding of blockchain fundamentals (consensus, gas, security)
• Experience with wallet integrations and token standards
• Solid programming skills in JavaScript/TypeScript and/or Python
• Strong problem-solving skills and attention to security
• A self-driven freelancer who can independently own and deliver Web3 projects
