Harald Reingruber

Medical 3D Visualization Expert

Dedalus HealthCare DACH

11/2020 – Present · Scharnstein, Austria (Remote)

• Led the technical transformation of Dedalus’ medical 3D visualization module: evaluated technology options and migrated a legacy C++/DirectX 9 codebase to Rust + WebAssembly + WebGL/OpenGL and TypeScript
• Repackaged the module as a framework-agnostic Web Component, now shipping in production in two host products (Angular- and React-based)
• Engineered a side-by-side comparison system enabling precise performance and visual validation during the migration
• Established a component-level E2E testing layer with Storybook and Playwright, replacing cumbersome end-to-end tests in host applications
