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.
I am always eager to learn and teach, so don't hesitate to reach me on Mastodon for any question or just to get news. You can also subscribe to my blog's RSS feed.
