Paul-Emmanuel in a few words

Self-educated since my childhood, I am a technology and science lover with a deep passion for IT, information security and open-source software, and I am also obsessed by automation. I write software, create learning content about IT-related topics and hunt for bugs.

My curiosity led me to work in different areas such as robotics, academic research and security engineering. I have never restricted myself to one specific topic, which translates my vision that everything is interconnected and that there are many ways to express our inner creativity. For this reason, I have always kept exploring new horizons in my spare time, creating and contributing to open-source projects, participating in technological and ecological groups, etc.

Sharing knowledge and experience is also something I am really attached to. This is why I started a blog in 2011 as a first way to contribute back to the community which allowed me to learn by myself. Since then, I continued creating content such as articles in magazines, presentations, interactive tutorials and hacking challenges. When I was working for Workday, I had the possibility to lead their global CTF hacking competition. I took this opportunity to create something even bigger by organising security workshops, monthly security quizzes and other innovative initiatives like the Malware Café, a pop-up coffee shop where people could come to see real-life hacking techniques in action to demonstrate the dangers of public places (and to enjoy a cup of coffee and some pastries of course!).

For many years, one after another, I worked for different companies, from startups to big multinationals. It was a great way to diversify my experience but I then decided to try something really different and challenging. This is how I became independent professionally speaking. I can now fully use my time to help people realise their projects, create even more content and focus on research.

Remi Leveugle - Lydia

8/16/2022

Paul Emmanuel worked with me (and more generally Lydia) for a bit more than 3 months. In a few days he was autonomous to work in our context, and was able to navigate in the company, finding the right persons to help him tech side. Paul Emmanuel met objectives we defined together and was able to adapt his priorities thanks to company priorities. He has really strong tech capacities (design, dev, devops). From a human perspective it was really great to work with him. I hope we will meet again in the future ! Thanks dude!
