Summary
👤
Senior🎓
Top SchoolAdam Schønemann is a Haskell developer with 13 years of software experience and an MSc in Computer Science from the IT University of Copenhagen, specializing in functional language design and implementation. He brings deep expertise in advanced type systems and languages such as Haskell, Elm, Coq, Idris and Purescript, alongside practical experience in TypeScript and Kotlin. At Deon Digital he applies this specialty in production, and his open-source work includes thoughtful contributions to the widely used Haskell aeson JSON library, where he improved time handling and leap-second parsing edge cases. Earlier roles combined systems administration and full-stack web development—building a custom intranet and scalable infrastructure for a high-traffic public venue—so he blends theoretical rigor with pragmatic engineering. He’s particularly interested in type inference, dependent types and principled recursion, making him well suited for projects that demand both formal correctness and reliable real-world performance.
