Intro

In this talk, Hugo Bowne-Anderson, an independent data and AI consultant, educator, and host of the podcasts Vanishing Gradients and High Signal, shares his journey from academic research and curriculum design at DataCamp to advising teams at Netflix, Meta, and the US Air Force. Together, we explore how to build reliable, production-ready AI systems—from prompt evaluation and dataset design to embedding agents into everyday workflows.

You’ll learn about:

• How to structure teams and incentives for successful AI adoption
• Practical prompting techniques for accurate timestamp and data generation
• Building and maintaining evaluation sets to avoid “prompt overfitting”- Cost-effective methods for LLM evaluation and monitoring
• Tools and frameworks for debugging and observing AI behavior (Logfire, Braintrust, Phoenix Arise)
• The evolution of AI agents—from simple RAG systems to proactive, embedded assistants
• How to escape “proof of concept purgatory” and prioritize AI projects that drive business value
• Step-by-step guidance for building reliable, evaluable AI agents

This session is ideal for AI engineers, data scientists, ML product managers, and startup founders looking to move beyond experimentation into robust, scalable AI systems. Whether you’re optimizing RAG pipelines, evaluating prompts, or embedding AI into products, this talk offers actionable frameworks to guide you from concept to production.
