Top SchoolPatrik Johansson is a cloud developer and architect specializing in 5G packet core systems, with over 20 years in telecom and software development and 12 years focused on cloud-native engineering. At Ericsson he has led architectural transformations from 3G/4G to LTE and now builds next-generation 5G core products in Go using Kubernetes, Docker and modern CI/CD practices.
