Hoi! I'm Jurgen Ploeger, a product designer in Amsterdam working on developer tools and AI products. I partner with founders and engineers on the surfaces where complex systems meet real users.
Setting the design standard for Stream's cross-platform SDK. I partner closely with engineering to build scalable design systems and ship production-quality UI components across every surface.
Cofounded Medivara, an AI tool that automates and summarises complex medical dossiers. Hands-on across product, brand, and GTM.
Shipped major surfaces of Humanloop's product alongside the founding team: prompt management, onboarding, and evaluation views. Humanloop was acquired by Anthropic in 2025.
Cofounded and ran Heavyweight, a design studio. Designed 150+ products across productivity, education, and health, working closely with founders and engineers.
