I'm a Full-Stack Software Engineer at DaleelTeq and an M2 Research Master's student in Data Science at ENSI (2026–2027). I also hold a Computer Engineering degree from ESPRIT.

My work spans two complementary areas: full-stack software engineering and Python-based machine learning / data science.

At DaleelTeq, I build and maintain enterprise applications using Java, Spring Boot, Angular, PostgreSQL, and Docker, with experience in both monolithic systems and microservices. I enjoy turning complex requirements into maintainable APIs, reliable backend logic, and useful interfaces.

Python is central to my data science journey. I've used it for machine learning, data processing, and analysis, including a customer churn prediction project. As an ENSI M2 Research student, I'm developing my foundations in advanced machine learning, computer vision, multidimensional signal processing, and data compression, with a focus on applying research ideas in practical experiments.

Beyond work and university, I practice data structures and algorithms on LeetCode and Codeforces, and I enjoy exploring new technologies and improving my problem-solving skills.

• 2026–2027 | ENSI — M2 Research Master's in Data Science (currently pursuing)
• 2022–2025 | ESPRIT — Computer Engineering degree
• 2018–2022 | ISET Charguia — Bachelor's degree in Information Technology

Mathematical foundations: Linear Algebra · Probability · Statistics · Optimization & numerical methods (areas I'm strengthening)

My goal is to build a strong bridge between software engineering and scientific research, especially through hands-on ML projects and future research collaborations.

Python is my main language for exploring machine learning and data science, alongside Java as my primary professional backend language.

• Hands-on experience: data processing, exploratory analysis, ML experiments, scripting, and prototyping
• Previous ML project: customer churn prediction using Python
• Current research direction: computer vision, signal processing, and data-driven modeling through my ENSI M2 studies
• What I'm building toward: stronger mathematical foundations, rigorous model evaluation, and reproducible research code

I don't treat one architecture as automatically better than the other.

I work with the architecture that best fits the application's scope and requirements — whether that's a structured Spring Boot monolith or a distributed microservices architecture.
