About Mohamed Yassine

Senior Data & AI Engineer with 8+ years of experience building scalable data platforms and production-grade AI systems, including LLM-powered applications.

I help companies design and deploy end-to-end solutions combining data engineering, machine learning, and Generative AI — from data pipelines to intelligent applications.

My expertise spans:
• Scalable data pipelines (ETL/ELT, Spark, Airflow, DBT)
• LLM systems (RAG, LangChain, tool-calling, agents)
• Data platforms and distributed systems on AWS & GCP
• Production ML systems and MLOps practices

I specialize in turning complex data and AI problems into reliable, maintainable, and production-ready systems used in real business environments across finance, automotive, and enterprise software.

Currently open to senior roles, freelance missions, and collaborations in AI and Data Engineering.
