As a freelance data science and ML engineering consultant, I use LLMs and AI coding tools across every phase of my work — from drafting client proposals, to formulating technical requirement docs, to scaffolding production data pipelines. In this session, I'll walk through my real workflows with concrete before-and-after examples, showing where AI tools genuinely compress weeks into hours and where they confidently generate garbage that an expert has to catch. You'll leave with a practical framework for integrating AI tools into your own professional practice — whether you're a solo operator, a small team lead, or just someone trying to figure out which AI hype is real.
