Two decades
of building

I'm Adao Oliveira Junior, a solutions architect and software engineer with more than two decades of experience building distributed systems, cloud-native platforms, and modern developer workflows.

My work spans architecture, product strategy, and developer adoption. At Oracle, I helped customers and partners turn complex technical requirements into production-ready cloud solutions at global scale.

Today I write, build under jun.io, and work on AI platforms, agent systems, and developer experience — independently and with select teams.

I also write, contribute to open source, and speak at events including KubeCon, Oracle Cloud World, Arc of AI, and developer conferences across the cloud-native ecosystem.
