Top SchoolJohn Vajda is an impact-driven Head of Product with 13 years of product leadership and 10 years of hands-on software development experience, specializing in developer experience, API strategy, and PLG growth.

He’s equally comfortable defining API standards and sprint-level engineering decisions, having implemented AsyncAPI/OpenAPI processes and led cross-functional teams. Based in Colorado, he combines product rigor with a hacker’s curiosity—recently accelerating feature delivery via prompt engineering and AI-assisted development.
