À propos de Baptiste
👋 AI Engineer — LLM, Fine-Tuning & Production ML
I build AI systems end-to-end: from data pipelines and model training to production deployment. I focus on getting things to actually work and ship.
- LLM & Generative AI — agentic workflows, RAG, tool calling, inference optimization (vLLM), secure deployments
- Model training & fine-tuning — LoRA, custom datasets, open-source models (text & image)
- Data pipelines — large-scale extraction, automated labeling, experiment tracking
- Production — API design, rate limiting, monitoring (Prometheus/Grafana), CI/CD
