Sebastien has been playing with computers since the beginning of the '80s. After spending some years with 8-bit processor assembly programming, he specialized in the 90 in C/C++ and i386 assembly on Win/Intel. During the Internet years, he participated in several startups and released some open source software, including a multi-platform XML parser written in C++. At this time, he was confronted by software pirates and the world of buffer overflows and SQL injections. In 2002, he switched to applications security and forensics and co-founded ADVTOOLS in Geneva. Since June 2014, he has worked as a security engineer for SCRT, a swiss company near Lausanne. He is also involved in feminine initiatives around Information Technologies and cyberfeminist groups.
