The RAG Reality Check: From Vibe-Coding to Production

Retrieval-Augmented Generation (RAG) is the gold standard for grounding LLMs in proprietary enterprise data. However, the journey from a flashy proof-of-concept to a reliable, secure production system is fraught with complexity. This talk bridges the gap between rapid prototyping and rigorous engineering. We will begin by exploring the actual merit of “vibe-coding”—using AI-assisted, rapid prototyping to build compelling demo apps that secure client buy-in and validate use cases.

Once the demo is sold, the real work begins. We will navigate the architectural decision matrix, comparing the trade-offs of off-the-shelf products, cloud-managed services, and fully custom-built RAG solutions. Diving into the technical pipeline, we will cover modern ingestion strategies like agentic chunking and sophisticated retrieval methods, including re-ranking and GraphRAG, to overcome the limitations of simple vector search. We will detail the essential role of telemetry and LLM-as-a-Judge evaluation frameworks in ensuring sustained performance, faithfulness, and relevancy. Join us to learn how to transition from impressive demos to robust solutions that deliver measurable business value.

Our Speaker, Dr. Enrico Fonda is a data scientist with a background in physics. He conducted postdoctoral research at the University of Maryland and New York University, where he studied quantum fluids and applied deep learning to turbulence. In 2019, Enrico moved to London and transitioned his skills to the industry. He has since worked across the MarTech, Telco, and Tech sectors, focusing on machine learning modeling, generative AI applications, and code generation. Today, as a Solution Consultant at Sahaj Software, he continues to solve complex problems in data science and AI.
