Additional Speaker Details
Using publicly available information we constructed an analysis to help you get a feel for this speaker before deciding to attend their session.
Fuentes Leone is an AWS GenAI Developer Advocate who builds and ships multimodal AI agents in production, and her sessions are hands-on and metrics-grounded: her re:Invent 2025 talks walked through live demos and real production outcomes (e.g. cutting deploy alerts from 200 to 5 and MTTR from 2 hours to 15 minutes) using the open-source Strands Agents SDK. Attend if you want concrete, runnable patterns for making agents reliable, observable, and cheap in production rather than vision-level theory.
