I'm a data and AI engineer, researcher, educator and speaker. I'm a doctoral student at POLI-USP, a Google Developer Expert and founder of IA Preta.
My work connects data architecture with the engineering of trustworthy systems: how they coordinate actions, preserve state and recover from failures. Here I share technical demonstrations, design artifacts and learning resources.
