I am a Senior Web3 developer specializing in secure smart contracts.
PakistanI am a results-driven Web3 developer with eight years building decentralized applications, secure smart contracts, and end-to-end blockchain systems.
I have engineered scalable smart contracts on Ethereum, Solana and Layer-2 chains, optimizing for gas efficiency, modular degradability, and secure execution. I led architecture and delivery of DeFi, NFT marketplace, and DAO systems using Solidity, Rust, Anchor, Web3.js, and Ethers.js.
I integrate blockchain solutions with backend services using Node.js, TypeScript, and GraphQL, implement cross-chain bridges and oracle integrations (Chainlink, Layer Zero), and build CI/CD testing pipelines with Foundry, Hardhat, and Truffle. I have led teams to launch multiple mainnet projects, contributed to open-source tooling, and worked on ZKP and formal verification workflows.
I’m driven to solve complex, security-critical problems and to ship production-grade dApps that scale; I thrive in collaborative, product-focused teams ready to innovate in DeFi, NFTs, and cross-chain infrastructure.
