I am a blockchain developer who has been obsessed with this technology since 2008, when I first stumbled upon Bitcoin as a curious kid with no resources—just raw fascination. That early spark never faded. It evolved into hands-on expertise across Ethereum, Solana, Polygon, BSC, Arbitrum, and even Hyperledger, with a recent deep dive into Rust and C++ to explore core blockchain architectures and consensus algorithms. I build things that live on mainnet. A land registration system with 4K+ deeds minted. An NFT marketplace with on-chain royalties. A staking dApp that hit $1.2M TVL across three chains. A Pump.fun sniper bot that executes in sub-second windows. A Solana whale tracker that parses blocks in 200ms. These are not tutorial projects—they are production systems handling real value and real users. My stack is Solidity, Rust, JavaScript, React, Hardhat, Foundry, web3.js, ethers.js, and AWS infrastructure. I write upgradeable contracts with 95%+ test coverage, optimize gas until it hurts, and treat security as a first-class feature. I have proposed Hyperledger for enterprise CRMs, deployed automated RPC clusters, and debugged bytecode at 2 AM so you do not have to. I am not a coder who happens to know blockchain. I am a blockchain native who learned to code. If your project needs someone who understands both the protocol layer and the user experience, who can architect a smart contract and then explain it to your investors, let us talk. I am available for full-time, contract, or advisory roles, and I start fast. Open to: Solidity audits, dApp architecture, mainnet deployments, cross-chain bridges, DeFi primitives, and anything that pushes this technology forward.
