Summary
🤩
Rockstar🎓
Top SchoolUtku Demir is a software engineer with 12 years' experience building reliable, composable systems using functional and pragmatic toolchains—writing Haskell at home and Scala at work. Based in Auckland, he has contributed to production-grade systems across startups and enterprises, from Spark-based batch pipelines to Kubernetes-backed virtual collaboration platforms. At Tweag and Picus he focused on correctness and composition with Haskell and Nix, and his open-source work includes meaningful back-end contributions to tweag/ormolu, improving formatting for advanced Haskell features. Comfortable across cloud and infra stacks (AWS, Terraform, Kubernetes) as well as low-level prototypes (Raspberry Pi, C), he brings both research-informed language design sensibilities and hands-on delivery experience. Colleagues know him for applying programming-language rigor to pragmatic engineering problems and for a quiet enthusiasm for sound abstractions.
