About Me

I'm Toka Sayed, a Web Penetration Tester and Computer Science student at Assiut University (Mathematics Dept.)

My journey spans hands-on penetration testing and ethical hacking, mobile development with Dart & Flutter, and frontend web development with HTML/CSS/Bootstrap.

I've trained with NTI (National Telecommunication Institute), Vodafone Egypt, and Google Developer Groups — building real projects, leading teams, and earning certs along the way.

Currently exploring API integration in Flutter and sharpening my security skills through TryHackMe.
