As Tech Lead at Bpifrance, a public investment bank. Our team comprised 6 members: 4 developers, 1 Product Owner, and 1 Scrum Master. Within this team, I conceived and deployed a conversational AI platform. This platform, centered around an intelligent chatbot, offers centralized access to a diversity of language models via a dedicated proxy. By employing RAG and function calling techniques, the chatbot can tap into an extensive internal and external knowledge base to furnish precise and contextual responses to collaborators. Chatbot ~1000 daily users Proxy ~10 consuming teams My responsibilities: - Construction of the project architecture - Development of the chatbot (Chainlit, Python) - Development of the RAG API (FastAPI, Python) - Development of agents (LangChain, LangGraph, FastAPI) - Development of CI/CD pipelines (Jenkinsfile, Jenkins, Gtilab) - Unit tests (Pytest, RAGAS) - Ensuring the technical quality of deliverables (Pair review, SonarQube) - Production deployment (Helm, Kubernetes) - Implementation of observability (Datadog) Technical context: Python, FastAPI, PostgreSQL, Kafka, Langfuse, Langchain, LangGraph, RAG, PyTest, RAGAS, Jenkins, Gitlab, AWS, Azure, Kubernetes, Helm, Flux, Datadog
