About
I started in growth marketing, running funnels, CRMs and content teams. The bottleneck was always production, so I began building the systems myself: LLM agents, multi-model image and video pipelines, and the internal tools that tie them to real campaign work.
Today I co-found and lead AI and creative at Deixa que eu faço, a service-marketplace app, and build brand-content systems for agencies and dealer groups. I’m also finishing a technology degree in AI and machine learning at FIAP.
