About Paul-Emmanuel
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.

- University College Dublin (UCD)Research EngineerRESEARCHDecember 2016 - February 2018 (1 year and 3 months)Dublin, IrelandI worked on a research study in respect to the EU fintech ecosystem.This project aimed to explore, using ontological modelling, the EU fintech ecosystem. It sought, inter alia, to improve our understanding of this ecosystem. The study suggested combining novel knowledge representation and data modelling techniques to reveal links between concepts represented in the data that otherwise were not accessible.To explore the data, I developed a web application called FintechBrowser which embodied the concepts explored in our study.▶ Software Development▹ Designed and developed FintechBrowser, the artefact which embodies our research study (TypeScript, Angular2, SPARQL)▹ Developed and deployed the official website of the study (Jekyll, GitHub Pages)▶ Data Modelling▹ Created the ontological model of the fintech ecosystem on which our study relied (RDF/OWL)▶ Systems and Networking▹ Set up the infrastructure used by our project (Docker, GitLab, Fuseki, WebProtégé)▶ Social Events▹ Presented and demoed our work at SEMANTICS 2017 (demo paper accepted)
