Rockstar🎓
Top SchoolDavid K is a CEO and seasoned software engineer with nine years of experience building DeFi infrastructure and blockchain tooling from NYC/Toronto while based in Canada. He has blended leadership and hands-on engineering across startups and open-source projects, including engineering roles at The Graph and Informal Systems and founding a stablecoin startup, Ekonomia. Technically versatile, he has shipped front-end analytics for Uniswap and contributed substantive back-end work to The Graph and the Cosmos SDK—fixing edge-case bugs, improving smart contracts, and enhancing core blockchain modules. Comfortable across the stack, he pairs UI/data-visualization work with low-level protocol fixes, a pattern that surfaces both product intuition and deep systems understanding. He currently runs Open Source Technologies, focusing on contract work and research that bridges developer ecosystems and production-grade decentralized systems. An engineer at heart, he brings entrepreneurial grit and a track record of making complex blockchain primitives practical and inspectable.
