👨🎓 Engineering degree from Institut Mines-Télécom in applied mathematics and computer science
As an experienced Fullstack Data Scientist, I develop, train, and deploy artificial intelligence models in cloud environments to solve complex problems and fully leverage business data. I have worked with startups and multinational corporations, covering all stages of the process.
I thus have complete expertise in artificial intelligence:
⛏️ data collection
🔍 analysis and visualization
🤖 machine learning & deep learning model training
🏗️ production deployment
all within a cloud environment, in a CI/CD context.
I can help you to:
📈 better understand your customers (customer segmentation, churn prediction)
📕 use NLP techniques to exploit vast corpora of textual data (such as customer feedback), particularly using LLMs like BERT, GPT, LLaMa, Mistral, etc.
🤖 implement an LLM-based application
📢 develop voice processing algorithms: speech recognition, speech synthesis (text-to-speech), etc.
🤝 Of course, I work closely with business teams and always keep in mind the business objective of a project.
✉️ Contact me to discuss how we can collaborate and fully leverage the power of your data!
