Árni Magnússon is a Senior Software Engineer and incoming Columbia University MSCS student with a decade of hands-on experience building full-stack web and mobile applications. He has shipped production React and React Native products—from a national hospital patient app used by a quarter of Iceland’s population to a free-form chat app at Daze—and has deep practical experience across frontend, database design (EdgeDB), and TypeScript-driven stacks. His background includes machine learning coursework at ETH Zürich and University of Iceland research that simulated kidney donation chains, blending algorithmic thinking with user-facing product work. At Fractal5 he wore many hats on a four-person team, driving UI, backend architecture, and product strategy, and even prototyped learning games inspired by spaced-repetition techniques. Now based in New York, he’s focused on scaling ML-informed features and broadening his systems and research depth during graduate study.
