2019
The Beginning
First Code & CS Path
Right after my BAC diploma, I discovered the magic of programming. Enrolled in Computer Science and never looked back — algorithms, late nights, and building things that work.
2021
The Builder
Freelancing & Woven
Started freelancing while launching Woven — a full e-commerce marketplace platform for mobile and web. Learning business by actually doing business.
2024
The Diploma
Computer Science License
Earned my Computer Science license degree. Years of code, exams, and side projects, finally stamped on paper — but the real proof was already in the things I'd shipped.
2025
The Crossing
Italy · Business Innovation
Flew to Italy with my friend Mohamed to represent our university at a business innovation event. Came back with something better than any prize — a room full of passionate people who think bigger than borders.
2025
The Arena
Algiers Hackathon
A few months later, back home, I went deep into a hackathon in Algiers. Sleepless nights, fast prototypes, real teammates. This is where my tribe started forming — people who think in code and dream in products.
