Summary
🤩
Rockstar🎓
Top SchoolJens Hausdorf is an IT-Security Consultant and Master's student with 11 years of hands-on experience blending DevSecOps, software supply-chain security, and pragmatic engineering. Based in Karlsruhe, he embeds security into agile development and cloud infrastructure, driving monitoring, analysis and ISMS-aligned controls at dmTECH/dm-drogerie markt. A versatile engineer, Jens contributes to both backend (PHP, performance micro-optimizations, language-server improvements) and frontend projects (VS Code icon theming, i18n), and has fixed subtle bugs in high-profile ecosystems such as the WoltLab core and Mozilla’s codebase. He built a multi-source vulnerability ingestion pipeline early in his career to shorten exposure windows across product teams, and has implemented audio/video and language-server features with unit tests in notable open-source repos. Known as “nerd by night,” he pairs curiosity about low-level formats (PNG, C++) with practical security tooling and developer-focused solutions.
