At Grupo Boticario, I led an internal B2B demand planning platform supporting decisions tied to $5B+ in annual revenue. I redesigned operational workflows, reducing planning cycle time from 40 to 20 days.

I also improved product stability by 60%, reduced cloud infrastructure costs by 20%, and simplified 50% of business rules. As Senior Data Product Manager, I helped develop an AI-native platform that increased operational efficiency by 25%.

At Micro 1, I evaluate LLM responses, create structured scoring rubrics, and provide human evaluations and preference rankings to support RLHF. I use AI-assisted workflows for product discovery and prototyping, including Claude, ChatGPT, and Amazon Kiro.
