Top SchoolJohan Hellgren is a hands-on technology leader and owner of Concepta Solutions with eight years of focused experience modernizing cloud-native platforms, developer workflows, and applied AI solutions. He combines strategic architecture and team-building with active coding in Go, Python, C#, JavaScript/TypeScript and Rust, and has driven a department from zero to 50 Kubernetes-based systems in production.
