Hello world, I am Guillaume, currently working as a software engineer in Zurich. Although I specialized in information security during my studies, with a master's thesis in cryptography, I am more broadly interested in many aspects of software engineering (see my open-source contributions).
My focus on what I would call "foundations" of software and security, has led me to work on a wide range of topics including cryptography, firmware, file formats, data compression, performance and privacy. But I also enjoy writing software higher up the stack, such as a 3D visualization of surrounding mountains with OpenGL.
I have published several research papers and given talks, notably on cryptography, file formats and privacy topics.
