Blockchain Engineer building secure smart contracts and full-stack dApps with Solidity, Node.js/Express, and React.
IndiaWhat I'm looking for
I’m a Blockchain Engineer focused on secure Solidity smart contract development and production-grade blockchain backends. I specialize in architecting dApps, implementing ERC token standards, and delivering reliable REST APIs powered by live on-chain data.
In my current Associate Engineer role, I’ve engineered and deployed 3+ Ethereum Solidity smart contracts with 90%+ test coverage using Chai and Mocha. I also built scalable Node.js and Express.js REST APIs that support 3+ client dApp projects.
Beyond Ethereum, I’ve authored TON smart contracts in Tact (Jetton and TEP standards), reducing client token deployment time by 40%. I’ve verified Solana smart contract functionality in Rust to support on-chain data integrity and security compliance.
I enjoy bridging blockchain and user experience—designing React.js/Next.js frontends connected via Web3.js for seamless on-chain interaction. I bring a security-first mindset, emphasizing testing, audit trails, and dependable system design to help teams ship confidently.
