Summary
🎓
Top SchoolJohannes Vollmer is a UX/UI designer and software engineer with 8 years of experience blending visual design and systems-level development, particularly in 3D, XR, and interactive interfaces. He ships pragmatic design systems and front-end experiences while also contributing low-level image processing code—most notably adding OpenEXR support to the image-rs Rust library, including f32/f64 pixel handling and performance-focused refactors. At SWCode he marries design and engineering, and as a consultant at E.ON he implemented a design system that unblocked trading software development. His background teaching visual computing and building OpenGL-ready Java libraries speaks to a strong foundation in graphics pipelines and developer tooling. Based in Germany, he combines hands-on prototyping for VR with production engineering, uniquely bridging creative interaction work and robust back-end integration.

Contributions summary:Johannes focused on implementing initial support for OpenEXR image format within the image-rs/image repository. They added OpenEXR decoding and encoding capabilities, including the necessary code for reading, writing, and handling image data. They introduced f32/f64 support for pixel components and updated dependencies to newer versions, with some refactoring for performance and cleaner code. Their work included both low-level byte manipulation and higher-level integration with the existing image library, covering decoding and encoding functionalities.
