About

I’m a Master’s student in Computer Science – Software Engineering for the Web (MIAGE) at Université Paris-Saclay (Évry campus). I’m deeply interested in building software systems that combine data analytics, web engineering, and artificial intelligence to solve meaningful problems.

Before that, I earned my Bachelor’s degree in Business Computing – Business Intelligence at IHEC Carthage, where I ranked top of my class multiple times and completed a capstone project on Smart Network Monitoring in collaboration with Amaris Consulting.

I enjoy working on projects that merge data, automation, and modern web technologies — from AI-powered career assistants to interactive analytics platforms. I’m also preparing for an internship in software or data engineering starting May 2026.
