Rockstar🎓
Top SchoolSimon Hausmann is a seasoned software engineer and co-founder based in Berlin with 27 years of experience building and maintaining core GUI, graphics and web-platform technologies. He has deep expertise in Qt and related ecosystems—having led QML and JavaScript engine work at The Qt Company and contributed to foundational projects like Sphinx, QtBase, QtTools and the widely used vcpkg. Simon blends hands-on backend, frontend and DevOps skills with strong build/release and cross-compilation experience, exemplified by work on rust-skia, corrosion and Yocto integrations. He favors small strike teams to tackle hard engineering problems and has a long history of improving deterministic builds, CI across platforms, and robustness in graphics/path rendering. An active open-source maintainer, he often fixes subtle platform-specific bugs (e.g., HTML logo/favicon handling, SVG arc edge cases) and adds unit tests that prevent regressions. His background in computational engineering and decade-spanning contributions to KDE, WebKit and Qt show a rare combination of low-level systems craftsmanship and product-focused leadership.
