Career & Capabilities

Building platforms, then learning to attack them

Software engineer with a Bachelor's degree in computer science and telecommunications, now in the second year of a Master's in Information Systems Security (MASSI) and specializing in web penetration testing. I build web and mobile platforms that run in production, deploy them myself on my own servers, and review them with an attacker's eye. Alongside that, I founded SINDA SARL, a digital engineering group focused on education.
