Hayab

I’m a Software Engineer specializing in blockchain development and Web3 solutions. My focus is on building secure smart contracts, scalable APIs, and decentralized applications that solve real-world problems. 🔹 Skilled in Solidity, Foundry, Hardhat, Move, and Go, with hands-on experience building ERC-20/721 tokens, DeFi protocols, and NFT marketplaces. 🔹 Experienced with backend systems (Go + Gin, Node.js, PostgreSQL/MongoDB) to power Web3 integrations. 🔹 Passionate about security-first development: I study common exploits (like wallet drainers, reentrancy, flash loan attacks) to write and audit safer contracts. 🔹 Contributor mindset — I thrive on building, testing, and deploying dApps, from hackathon prototypes to production-ready protocols. Whether you need a smart contract developer, blockchain auditor, or full-stack Web3 engineer, I can bring ideas from concept to launch with a focus on security, performance, and user trust.
