Top SchoolManuel De Brito Fontes is a seasoned cloud-native engineer and open-source maintainer with 13 years of hands-on experience building and operating production Kubernetes infrastructure. He created and led the widely used NGINX Ingress Controller project and has deep roots in early cloud-native projects like Deis, CoreDNS and kops, with contributions that span load balancers, CRDs, CI/CD and dependency modernization. Equally comfortable coding and operating, he focuses on reliability, build automation and scalable networking primitives—often fixing subtle runtime issues like zombie processes, conntrack tuning, and port-collision bugs. A founder and CTO with successful SaaS exit experience, he blends product instincts with practitioner-level DevOps skills and community leadership. Based in Santiago, Chile, Manuel has a track record of shepherding large open-source communities (thousands of contributors and millions of downloads) while still contributing practical engineering patches and automation.
