Senior🎓
Top SchoolRafael Barbosa is a senior Financial Services Solutions Architect at AWS in São Paulo with eight years of hands-on experience designing secure, cost-efficient cloud architectures for large banks and fintechs. He leads high-stakes programs where small technical choices affect regulatory compliance and operational risk, delivering outcomes like rapid BACEN/PIX audit homologation with CloudHSM, 30%+ EKS cost reductions via workload-tuned Karpenter, and multi-region resilience strategies.

Previously he drove migrations and payments cryptography modernization that cut card-processing costs by over 40%, and has enabled GenAI acceleration for docs and legacy-code workflows using Amazon Bedrock and Q. He also teaches MBA courses at FIAP and USP/Esalq—reaching thousands of students yearly—and translates real-world FSI constraints into practical decision frameworks. Outside of AWS he remains a developer and DevOps enthusiast, organizing community meetups (churrops.io) and focusing on production big-data architecture.
