Throughout my career I have continuously contributed to the creation of secure systems, either as a software engineer, a technical lead or a security consultant.I enjoy working on about everything related to application security, cryptography, security protocols, algorithms and networking code performance and robustness. While I work mostly on low-level code, I have authored or contributed to about a dozen different implementations of custom authentication/identification/authorization systems and many other security features for Web applications.I graduated in mathematics and I love science. I am an avid learned. I occasionally read scientific studies as a hobby.Last but not least, I like to make new acquaintances from all over the world.
