Freelancer profile translated to English.

Description

👋 I am a freelance data scientist and data engineer, with 8+ years of experience on projects combining massive data processing, predictive modeling, and AI solution integration.

🛠️ I design robust and scalable data pipelines (Spark, dbt), while maintaining a product and usage-oriented vision. I work on both ingestion (batch or stream) and the structuring of warehouses and the industrialization of analytical flows.

📈 On the data science side, I develop predictive models (time series, scoring, anomaly detection) and design AI applications around LLMs: intelligent assistants, semantic search (RAG), vector DBs, LangChain...

⚡ My approach is end-to-end: I quickly deliver usable MVPs via FastAPI or Streamlit, with a constant focus on clarity, maintainability, and business impact.

🧠 More than just code

I know how to challenge needs, maintain a clear product vision, and deliver useful, reliable, and scalable solutions.
