About Matthieu

🧑Who am I?
Holder of a PhD in applied mathematics and an artificial intelligence specialist, I have developed expertise in AI and learning algorithms. My career has led me to work for leading organizations such as Criteo AI Lab and the Swiss Federal Institute of Technology Lausanne (EPFL), where I applied advanced AI methods to real-world problems.

👉Today,I assist companies that wish to leverage the power of data and AI to optimize their decision-making processes and create high-performing predictive solutions. (LLM, RAG SLM, basic ML models)

Methodology
We begin with a free, no-obligation discovery call to understand your business, your specific challenges, and your goals.
I then conduct an in-depth analysis of your data and processes, collaborating closely with key stakeholders during an on-site workshop.
I provide you with a detailed strategic report that not only identifies areas for improvement but also establishes a concrete and actionable roadmap. Together, we define relevant performance indicators to measure the impact of the solutions.
For implementation, I adopt an agile approach that allows for rapid delivery of tangible results, continuously adjusting solutions based on your feedback and evolving needs.

⭐My areas of expertise include:
Predictive modeling and time series
Customer segmentation and unsupervised learning
Contextual bandits and optimization
RAG and fine-tuning of language models (LLM)
Computer vision and deep learning
