About Pierre

Full-Stack Developer with 10+ years of experience, primarily backend (Node.js, Java, MongoDB, Elasticsearch, Kafka). Passionate about distributed systems architecture and algorithmic optimization, I have notably designed deep learning pipelines to improve a production search engine. Curious about modern AI approaches (LLM, RAG), I am seeking an ambitious technical role where backend engineering and artificial intelligence converge.
