He focuses on spec-driven development to help engineering teams eliminate boilerplate and automate their integrations. Before *codeplain, he built production machine learning systems for national security and medical imaging apps. He currently works with agentic skill frameworks to turn structured specifications into automatically validated code generation. By treating the spec as the ultimate source of truth, he ensures AI-generated implementations actually work before they ship. ## Past Sessions ### World Congress 2026 Europe · July 8, 2026 Berlin, Germany - [Spec-Driven Development with Agentic Skills](https://www.wearedevelopers.com/events/world-congress-2026-europe/sessions/1144-spec-driven) · 120 min ## Links - [LinkedIn](https://www.linkedin.com/in/zan-jonke/) - [Blog](https://blog.codeplain.ai/)
