Senior🎓
Top SchoolJohn Butler is a Principal Solutions Architect at AWS with 11+ years of experience shepherding large enterprises through cloud, IoT, serverless and generative AI transformations. He previously served as a Technology Fellow and Chief Architect at Goldman Sachs where he designed and launched a cloud-native Transaction Banking platform covering payments, core banking, KYC and fraud. His background includes senior architecture and platform leadership across Citi and Credit Suisse, driving global standards for microservices, PAAS, DevOps and regulatory programs like FATCA. Comfortable as a customer-facing “CTO,” he blends hands-on engineering with strategic product and vendor decisions for complex, regulated financial systems. Based in the New York metro area, he pairs deep middleware and integration roots with modern cloud-native practice—a rare bridge from CORBA-era platforms to today’s serverless and IoT stacks. Outside of roles, his career shows a consistent pattern of building new platforms and practices from the ground up rather than incremental maintenance.
