👋 Hi, I'm Jean

I'm a Data Scientist Consultant at Orange Business, where I build production-grade AI systems. I recently shipped a RAG pipeline and I'm currently deep into agentic architectures: autonomous systems that reason, plan, and act.

💼 What I Do

At Orange Business, I work on applied AI projects at enterprise scale, from designing retrieval-augmented generation pipelines to building multi-step agent workflows. I care about turning research-grade AI into robust, deployable systems.

My background includes:

  • 🤖 Agentic systems - LLM-driven workflows that reason and act autonomously
  • 🔎 RAG pipelines - semantic retrieval, vector stores, document processing
  • 🔤 NLP at scale - keyword generation, semantic search engines, dense vector representations
  • ☁️ Cloud-native deployment - Python apps, APIs, CI/CD on AWS and Azure

🧰 Tech Stack

🔧 Data Engineering

Python Scraping Docker FastAPI SQL AWS Azure Linux DevOps Git Apache Airflow Apache Spark Prefect

📊 Data Analysis

Pandas NumPy SQL Tableau Power BI Jupyter

🤖 Data Science & ML

Hugging Face scikit-learn spaCy NLP LLM RAG Agents ML & DL TensorFlow PyTorch LangChain

🗺️ My Journey

Before Orange Business, I spent 4 years as an NLP engineer at Verbolia, a Belgian AI-SEO startup that auto-generates optimized landing pages for major e-commerce brands. That's where I built my foundation in semantic search, keyword systems, and production NLP pipelines.

In between, I took a year off in New Zealand on a Working Holiday Visa, one of the better decisions I've made.

I then joined BeCode as a Data Science & AI coach, guiding career changers through machine learning, cloud, and MLOps.

🎓 Coaching Philosophy

I believe learning by doing is the most effective path. My goal as a coach was to bridge the gap between theory and practice, encouraging students to build real-world solutions, write clean code, and understand the why behind the tools. That mindset still shapes how I work today.

🧠 Always Learning

Currently exploring:

  • Agentic frameworks - multi-agent orchestration, tool use, memory systems
  • LLM evaluation - measuring and improving agent reliability
  • MLOps - making AI systems production-ready at enterprise scale
