Software engineer, security researcher, digital investigator.
I currently work as a Cybersecurity and Tech expert at the Parquet National Financier in Paris, aiding judicial officers in high-stakes financial and corruption investigations—extracting insights from seized digital media, handling data leaks, and building analytical models to surface signal in large datasets.
Before that, I worked for nine years as CTO of Data Theorem, where I built and led the release of several cybersecurity SaaS products dedicated to securing mobile, web, API, and cloud applications at scale.
Before that, I spent several years in application security, mobile platforms, and the cryptographic plumbing that holds the modern internet together — auditing client/server software, breaking and fixing TLS implementations, and writing open-source tools.
I am occasionally available for consulting work, and I sometimes write technical articles at In Security.
Tools I've authored or maintained over the years, used in the security community for testing TLS configurations and mobile applications.
I've presented at Black Hat USA, Hack in the Box, BlueHat, OWASP AppSec, Ruxcon, and Cloud Expo, mostly on TLS, iOS internals, and mobile security research. I was also the technical reviewer for iOS Application Security (No Starch Press, 2016).
