    Software Engineer

    United States - Last active: 23 days ago - Tests: 1

    My primary job is developing an anti-tamper, anti-circumvention, and code/data obfuscation product based on a custom version of the Clang/LLVM toolchain. This product protects application binaries from reverse engineering, code lifting, IP theft, and cracking. I am a proficient reverse engineer (both static and dynamic techniques) and understand security from both the white hat and black hat sides. I have assisted in PS3 jailbreak development and DRM reversing for interoperability purposes. In addition to my low-level toolchain and security expertise, I have extensive experience with Verification and Validation from my prior work at Qualcomm and Delphi Electronics. Besides my educational and work experience, I am skilled in writing web scrapers, automating utilities, and simulation / data analysis.

    Gregory D.

    Consultant

    Switzerland - Last active: 11/07/2014 - Portfolio: 4

    After having started to program in C++ 2002, I started working in the domain of software development in 2003. Most of my earlier projects were for high-energy physics research, laying the groundwork for my specialization in data analytics. Over time and at first only out of curiosity I gradually switched towards security related areas such as reversing, penetration testing and of course cryptography. Several years later, by the time the global eavesdropping programs of many secret services around the world were revealed, I decided to focus on consulting for cryptography and other information-hiding approaches as my second area of expertise.
