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 understanding of data processing.<br><br>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.
