I build Web3 products end to end — DeFi platforms, NFT marketplaces, DEXs, and trading systems — along with the smart contracts and front-ends that run them. On-chain, the stakes are different from normal web work: a mistake doesn't show up as an error message, it shows up as money leaving someone's wallet. I build with that in mind, because once a contract is deployed there's no quiet hotfix. Six years and 20+ contracts in, my work splits two ways. Sometimes a team has an idea — a token, a marketplace, a protocol, a bot — and needs it built properly from zero: the contracts, the wallet flows, and the dashboard people actually trade on. Other times someone already has something half-finished or freshly audited and needs a developer who can read on-chain code carefully and get it to production without breaking what already works. The second one is where I'm strongest — understanding code I didn't write and finding what's genuinely wrong is most of the job. Some of what I've shipped: I led the front-end for Singularity Finance and SingularityDAO, integrating staking, vaults, and governance against live Ethereum contracts with real funds moving through them. I built a full NFT marketplace solo — minting, IPFS storage, and royalty logic, end to end. And I built DEX trading automation that monitors live pairs and executes on-chain. Off-chain, I've also delivered React Native apps live across 8 countries for PepsiCo, a Fortune 50 company — which is where I learned what production actually demands beyond the happy path. My stack is Solidity and Ethers.js on-chain, React, Next.js, Node, and TypeScript around it, across EVM chains and Solana. I use Claude Code to move quickly and check every line it produces — which is also why taking over a codebase another developer or an AI started doesn't worry me. What you're hiring is someone who treats your contracts and your users' funds with the seriousness they need, ships it right, and stays reachable after the deploy. Tell me what you're building.
