What I'm looking for

I'm looking to transition into full-time vulnerability research, with opportunities to investigate Windows, Linux kernel, container, and sandbox security. I'm available for remote, hybrid, on-site, or relocation-based roles.

I discovered CVE-2026-50416, a Windows 11 kernel pointer disclosure readable from Low Integrity, AppContainer, and LPAC processes, and produced a reproducible proof of concept and technical write-up.

I've assessed Docker-based execution environments at Technische Hochschule Ingolstadt, identified sandbox escapes and information disclosures, and tested Linux kernel CVEs against hardened containers. After six years of reverse engineering and software-security work, I'm studying Computer Science and looking to move into full-time vulnerability research.
