The website appears to be the portfolio of a French frontend engineer named Christopher Chedeau, also known as Vjeux. He works at Facebook and has contributed to numerous projects and initiatives in his role. The site includes information about his work experience, curriculum vitae, talks he has given, reports he has written, and various projects he has been involved in. Some notable contributions include improving Facebook's tagging flow with face detection technology, optimizing image sizes for efficiency gains in bandwidth and storage usage, promoting React (a JavaScript library) by organizing the first React conference and being part of the team behind Create React App and React Native. Additionally, Chedeau designed core components for animation libraries and spearheaded the CSS-in-JS movement. He was also involved in bringing the Prettier JavaScript pretty printing library from prototype to widespread adoption within Facebook. It seems that Chedeau is actively engaged in open source initiatives throughout his career.
