Paul Iusztin

Maxime Labonne, a Senior Staff Machine Learning Scientist at Liquid AI, and Paul-Emil Iusztin, founder of Decoding ML, delve into the fascinating world of AI application development. They tackle the complexities of deploying AI models, from understanding fine-tuning nuances to the critical RAG feature pipeline. Strategies for effective problem definition and the importance of scalable solutions are highlighted. The discussion also covers managing deployment costs and the balance between safety and model customization, making the technical accessible and engaging.

Paul Iusztin, founding AI engineer and author of the LLM Engineer’s Handbook, outlines the full-stack AI engineer skill stack and the shift from proofs-of-concept to shipping production-grade AI. He covers when classical ML beats LLMs, building reliable agentic workflows and knowledge pipelines, using AI assistants as architects, and creating a “Second Brain” portfolio to prove end-to-end engineering value.

Paul Iusztin, an AI engineer with eight years in the field, discusses the need to bypass common frameworks and fine-tuning in AI development. He emphasizes a hands-on approach, advocating for intuition over imitation to foster true innovation. His mantra? Build quickly, then refine without over-reliance on tools. The conversation also touches on the challenges of integrating large language models, the importance of tailored solutions, and innovative writing assistant development. Paul’s insights challenge the status quo and inspire a fresh perspective on AI production.
