ABOUT ME
Originally from the beautiful coast of Algeria, where I spent my youth free diving and fishing, I have always been drawn to exploring new depths — both in the sea and in data.
My early passion for computers and mathematics evolved into a pursuit of AI and data engineering. After earning a Bachelor's in Mathematics and Informatics in Algeria, I moved to Belgium to study Applied Computer Science (AI) at Thomas More — where I discovered my true interest in the modern data stack.
Following my internship at Algorhythm, where I built ELT pipelines, implemented medallion architecture, and worked with Spark, dbt, and Airflow, I relocated to France to pursue a Master's in Expert Systems (AI) at EPSI. I am currently looking for an apprenticeship (alternance) in Data Engineering or Analytics Engineering.
I am passionate about building reliable, well-structured data systems — from ingestion to transformation to insight — and I enjoy the challenge of making data trustworthy and useful at scale.
