I am a Senior Security Specialist for Secura, a security company based in the Netherlands. I regularly perform network pentests, web/mobile application assessments, as well as code, configuration and design reviews for large Dutch companies and instutions. My primary areas of interest include crytographic protocols and cryptography engineering, advanced web attacks and Windows AD pentesting. Besides doing security assessments, I also develop and give secure programming courses to software developers. Next to my job at Secura, I also work as a PhD student at the Amsterdam UMC hospitals, where I do research on cybersecurity within the medical domain.
