Freelancer profile translated to English.

Description

I help you transform your data into concrete levers for decision-making, optimization, and innovation.

🎯 What I bring you:

- Custom AI models (machine learning, NLP, time series) to automate your processes, predict your sales, or understand your customers.

- Clear and visual analyses to make your data speak and convince your stakeholders.

- Production deployment: from extraction (SQL, GCP, AWS) to putting your models into production (API, Pinecone, OpenAI, Airflow).

💡 What sets me apart:

- A dual technical & analytical skill set: a graduate of ENSAE Paris (statistics, economics), with 4 years of experience in various environments (startups, ministries, large corporations).

- An ability to explain complex subjects simply, so your teams can adopt the results.

- A rigorous, documented, impact-oriented approach.

🔧 Types of projects recently completed:

- Sales prediction for a travel marketplace (regression, A/B tests).

- Document matching & automatic summarization via LLM (OpenAI, Pinecone).

- Scoring of at-risk ships for the French State (classification, visualization with Metabase).

- Detection of rare cancers via an econometric model.

📊 Tools mastered: Python, SQL (BigQuery), Tableau, GCP, AWS, Airflow, scikit-learn, PyTorch, OpenAI, Pinecone.
