After writing code and optimizing applications for two decades, he now focuses on the practical mechanics of vector search and large language models. He regularly teaches developers how to build their own Retrieval-Augmented Generation (RAG) chatbots from the ground up. Using tools like Langflow and Astra DB, David shows teams how to move quickly from abstract AI concepts to rapidly deployed applications. ## Past Sessions ### World Congress 2024 · July 17, 2024 Berlin, Germany - [Hands-on Workshop: Build-your-own-RAG in minutes](https://www.wearedevelopers.com/events/world-congress-2024/sessions/5-hands-on-workshop) · 120 min - [Hands-on Workshop: Build-your-own-RAG in minutes](https://www.wearedevelopers.com/events/world-congress-2024/sessions/12-hands-on-workshop) · 120 min - [Accelerating GenAI Development: Harnessing Astra DB Vector Store and Langflow for LLM-Powered Apps](https://www.wearedevelopers.com/videos/966-accelerating-genai-development-harnessing-astra-db-vector-store-and-langflow-for-llm-powered-apps) · 30 min · 🎥 Watch recording ## Videos - [Accelerating GenAI Development: Harnessing Astra DB Vector Store and Langflow for LLM-Powered Apps](https://www.wearedevelopers.com/videos/966-accelerating-genai-development-harnessing-astra-db-vector-store-and-langflow-for-llm-powered-apps) · David Leconte, Michel de Ru
