À propos de moi
Most teams hire twice: once for the chain, once for the product. I am the engineer who covers both.
50+ production builds at OptimusFox since December 2021, plus 64 Fiverr projects at a 4.9 rating.
ON CHAIN: 15+ Solidity contracts, ERC20, ERC721, ERC1155, ICO and vesting, upgradeable proxies, DAO governance, a Uniswap v3 clone, cross-chain bridges and Hyperledger Fabric.
ON PRODUCT: NestJS and PostgreSQL APIs, React and Next.js front ends, and the Web3 integration that joins them. Recently TVET MIS, a national government skills platform.
Tell me what you are building.
