Rockstar🎓
Top SchoolAleksander Heintz is a seasoned consultant and software engineer based in Oslo with 15 years of experience delivering back-end and full-stack solutions across .NET, compiler tooling, and cross-platform projects. He has a strong track record in improving developer tooling and runtime behavior, contributing to notable open-source projects such as React.NET, OmniSharp (Roslyn), Fable compiler, and MessagePack-CSharp.

With a Master’s in Computer Science from NTNU and long-standing consulting roles, he brings both deep technical chops and client-facing delivery experience.
