Cédric Van Rompay

Software Engineer (full stack + cryptography + security) ─ Paris, France

19 janvier 2024 : publication de « Une démonstration intuitive du théorème de Pythagore »

Since January 2022, I am working as a Security Engineer at Datadog in the “software integrity and trust” team. Some of my contributions can be seen in my work GitHub account.

Before that, I had been working since April 2019 as a software engineer specialized in cryptography and cyber security in general at Misakey, a French startup which goal was to make an end-to-end encrypted platform for people to manage their personal data on the Web. See this article for more details on my work at Misakey. Misakey closed in July 2021.

From 2014 to 2018, I was a PhD student at EURECOM. My field of study was cryptography, and my supervisors were Refik Molva and Melek Önen. See my PhD thesis, Multi-User Searchable Encryption.

Even before (2011-2014), I was an engineering student at Télécom Paris and EURECOM.

You can find me on the Web on the following networks: LinkedIn, StackExchange (StackOverflow etc …), GitHub, GitLab, Matrix/Element Chat (formerly Riot), Twitter.

Personal Side-Projects

A few projects I am working on on my free time:

You can see a more complete list of my personal projects, and their source code, on my GitLab.com profile.

I have a blog, mostly about technical topics. I don't write a lot in it for the moment.

I have a list of “things I like” (version française: une liste de choses que j'aime) if you're looking for nice content.

I would like to start writing a bit of popular science content, so I started with Une démonstration intuitive du théorème de Pythagore (an intuitive proof of Pythagoras theorem — in French).
