Dan Geabunea

Dan Geabunea is a Java Architect and Tech Lead with 15+ years designing and leading distributed systems for European enterprises in regulated, safety-critical domains. He coaches engineering teams on adopting AI-assisted development productively — helping developers integrate tools like Claude Code into real codebases, not toy examples. His hands-on approach to AI adoption has delivered measurable results: 30% improvement in team delivery efficiency, with 100% of developers reporting 20%+ productivity gains across code scaffolding, bug fixing, architectural documentation, and complex feature implementation. His courses focus on fundamentals that remain valuable regardless of how quickly the tooling changes: Java internals, Spring Framework, SOLID principles, software design, and automated testing. He holds an iSAQB CPSA-F certification in software architecture. If you're a Java developer who wants to write code that's easier to test, maintain, and hand off — to a teammate or an AI tool — Dan's courses are built around exactly that.
