Ryan Kim
Smart Contract Engineer
I craft the building blocks of a decentralized future.
About
I am a California-based Smart Contract Engineer with4 years of professional experience in designing and developing decentralized finance applications and blockchain-related projects. Proficient in developing EVM-based smart contracts and well-versed in programming languages such as Solidity and TypeScript, and skilled in smart contract development tools such as Foundry and Hardhat.
From on-clay to on-paper to online to onchain, the evolution of record-keeping has reached its most secure and transparent form with blockchain technology. My expertise lies in creating robust, efficient, and secure smart contracts that form the backbone of decentralized applications. I am committed to pushing the boundaries of smart contract development, constantly exploring new ways to leverage its revolutionary potential.
