Top SchoolRaymond K is a software engineer with six years of experience building performant, scalable JavaScript applications and developer tools from NYC. He has deep front-end expertise (React, TypeScript, Redux, Next.js) and a proven track record improving app performance and maintainability through tooling, AST-based analysis, and algorithmic refactors. As a core contributor to Reactime, he led its TypeScript migration, expanded Hooks/Context support, and engineered middleware to capture React fiber snapshots for time-travel debugging—work that helped the project earn a productivity nomination at React Summit’s Open Source Awards. Raymond thrives on cross-functional teams in mission-driven organizations, prioritizing clear interfaces, testability, and CI-driven deployment pipelines. His background in international studies and languages gives him a pragmatic, curious approach to problem-solving and collaboration across diverse teams. Outside of code, you’ll likely find him exploring NYC’s food scene while thinking about web performance.
