I enjoy working on security topics relating to bits and bytes such as crypto exploit dev, fuzzing and binary instrumentation. I have presented at several security conferences (Defcon, Nuit Du Hack, Shmoocon, ...) on the above topics. I also have written more or less useful security tools such as numstitch, scapy-http2, fuzzmon… as well as contributed to some open source security tools (scapy-ssl_tls, run tracer, afl…) In my day job, I work for Citrix Systems, taking care of product security.
