Researcher at Institute for AI Policy and Strategy (IAPS)
Berlin, Germany
Summary
🤩
RockstarErich Grunewald is a researcher and software engineer based in Berlin with 11 years of experience bridging applied research, trading infrastructure, and product-grade software development. Currently at the Institute for AI Policy and Strategy, he applies technical depth to export controls and AI policy questions, pairing domain knowledge with hands-on engineering. His background includes senior infrastructure work at Temple Capital and long-form engineering at Futurice, where he built reliable systems at scale. An active open-source contributor, he improved type safety in the widely used ReactiveObjC reactive framework by refining generics and covariance in core signal types. Known to describe himself wryly as a “first-class second-rate programmer,” he brings practical humility and a strong focus on making complex systems safer and more maintainable. He blends research instincts with production experience, making him adept at turning policy problems into verifiable technical solutions.

Contributions summary:Erich primarily focused on enhancing the codebase by introducing and modifying generics within the ReactiveObjC framework, specifically within `RACSubject`, `RACReturnSignal`, and `RACEmptySignal`. Their contributions involved refining the type annotations and adjusting the covariance of generic types to improve code safety and clarity. These changes demonstrate a solid understanding of generics and how they can be used to improve the type safety of a reactive programming framework. The user also merged changes from the master branch, integrating other potential modifications.
