About
Professional summaryI am a data engineer with over 4 years of experience building large-scale data pipelines and analytics platforms.
I have spent the last 3 years working in real-time streaming production, mainly with Kafka and Spark Structured Streaming, on telecom anti-fraud use cases.
My hands-on experience includes detecting SIMBOX, SIM cloning, and fraudulent usage on high-volume CDR streams, with a strong focus on reliability and low-latency processing.
I also have a solid background in batch ETL/ELT, data warehousing, and cloud deployment, especially with Informatica, Teradata, and GCP.
I enjoy designing end-to-end data architectures, optimizing performance, and making data systems scalable, fault-tolerant, and production-ready.
I have worked in international environments across Algeria, Belgium, and France, and I am authorized to work in France and available immediately.
