Sébastien became interested in computers in the early 1980s. After spending some time programming 8-bit processors in assembly, he turned to C and C++ in the Win/Intel world. During the Internet years, he participated in several startups and discovered the world of hacking, buffer overflows, and SQL injections. In the early 2000s, he founded a company specialized in information system security. Since 2007, he has been primarily focused on reverse engineering and forensics, particularly on mobile platforms (iOS and Android), developing solutions that blend high-level languages such as Objective-C or Java with C++ and ARM assembly.
