Tahir Aboukhassib
ING3 at EFREI Paris — Networks & Cybersecurity · IT apprentice at Génie Flexion
I practice cybersecurity day to day — audit, detection, automation, exploitation — with the ambition of moving toward pentesting and infrastructure security. Full-stack development in ASP.NET Core / Blazor is both a tool I've mastered and the ground on which I apply that security mindset. This site itself is meant as proof of technical skill as much as a showcase.
