Summary
🤩
RockstarTobias Oberstein is a Senior Software Engineer and long-time OSS maintainer who specializes in securing autonomous AI agents via a novel Dual-Confinement Security approach that monitors and controls both communication boundaries and directions. With 14+ years delivering high-performance messaging, real-time microservices and data platforms, he has led Crossbar.io and Autobahn development, built WAMP-based middleware for automotive and IoT, and modernized secure stacks for a U.S. defense contractor aligned to NIST and SLSA requirements. He combines deep hands‑on skills in Python, Java, WebSocket/WAMP, distributed systems and CI/CD with practical experience in high-throughput databases and embedded Linux. Tobias advises and builds architectures that translate regulatory standards (MaRisk, BAIT, EU AI Act) into auditable AI confinement patterns and tooling. An active GitHub contributor, he has improved Autobahn test suites and core libraries, and quietly bridges protocol-level robustness with security-minded operational controls. Based in Bavaria, he pairs pragmatic engineering with a contrarian drive to reshape how safety and trustworthiness are enforced in autonomous systems.
