I’m Raphaël LACROIX, a French computer scientist developping various applications in my free time ranging from definitely useless to somewhat usefull. I also do quite a lot of Capture the flag and cybersecurity challenges. I am currently looking for a Penetration Tester position in Toulouse (or in full remote).
