Lazar Jovanovic is a full-time professional vibe coder at Lovable. His job is to build both internal tools and customer-facing products purely using AI, while not having a coding background. In this conversation, he breaks down the tactics, workflows, and framework that let him ship production-quality products using only AI.
*We discuss:*
1. Why having no coding background can be an advantage when building with AI
2. Why most of your time should go to planning and chat mode, not prompting
3. What to do when you get stuck: his 4×4 debugging workflow
4. The PRD and Markdown file system that keeps AI agents aligned across complex builds
5. Why kicking off four or five parallel prototypes is the best way to clarify your thinking
6. Why design skills and taste are going to be the most important skills in the future
7. His “genie and three wishes” mental model for making the most of AI’s limitations
8. How product, engineering, and design roles are converging—and what that means for your career
