Summary
🤩
Rockstar🎓
Top SchoolSebastian Schuberth is a co-founder and CTO with 20 years of engineering experience, blending hands-on full‑stack development with leadership in open source compliance and tooling. Based in Berlin, he has led Open Source Engineering efforts at HERE and Bosch.IO and now builds an enterprise-ready SaaS around the OSS Review Toolkit at Double Open. A pragmatic systems thinker, he moves easily from low-level performance and Windows build automation to Kotlin-based CLI libraries and cloud-ready backend tooling. His prolific open-source contributions span high-profile projects like Gradle, Git for Windows, libgit2 and the ScanCode Toolkit, often improving cross‑platform builds, CI and developer UX. He’s equally comfortable writing clear technical documentation and refactoring build systems as he is shipping product; an unexpected strength is turning complex compliance workflows into automatable, user-friendly services.
