Vianney - Data & AI Engineer

I build production-oriented data and AI systems that transform raw data into reliable pipelines, intelligent applications, and deployable machine-learning services.

My work focuses on data platforms, real-time processing, LLM applications, AI agents, RAG systems, and MLOps, with a strong emphasis on Python, AWS, distributed systems, APIs, testing and automation.


🚀 What I Build

  • Data Engineering — batch & streaming pipelines, ETL/ELT, data lakes, distributed processing
  • AI Engineering — LLM applications, RAG pipelines, AI agents, tool calling, and evaluation
  • ML / MLOps — model training, experiment tracking, model serving, monitoring, and CI/CD
  • Cloud & Backend — AWS, containerized services, REST APIs, and cloud-native architectures
