ABOUT GUILLAUME L.

With over 6 years of experience as a Data Scientist / ML Engineer within the e-commerce industry (Cdiscount & ManoMano), I have been managing entire projects from leading discussions with product teams to developing and industrialising algorithms in production, while also conducting A/B tests to validate the methods. I have developed a strong expertise in building Machine Learning / Deep Learning pipelines, particularly in the field of Search & Recommendations - Document Clustering (TF-IDF, Sentence Transformers)- Ad-hoc Retrieval (LightGBM Learning-to-rank)- Sentiment Analysis (BERT)- Attribute extraction through LLM fine-tuning - Similar Product Recommendation (Link prediction / Graph theory)- Personalized recommendations in real-time (Two-Tower architecture) Other projects include - Client Segmentation (ACP, Clustering)- Automatic Landing Page Creation & Quality Scoring (XGBoost classifier)- Image generation (Stable Diffusion) followed by Object Detection & Closest Product Image search All these projects have also allowed me to further deploy my skills in Python but also technos such as Docker, Airflow or Kubernetes because as a Data Scientist at Cdiscount / ManoMano, you\'re more of a Machine Learning Engineer with a very important part of the job being the deployment pipelines in Production. It also enabled the development of my communication, autonomy and leadership skills, by working with different entities (Product & Business partners), organizing projects and bringing ideas to the table in the process.
