Summary
👤
Senior🎓
Top SchoolSivan Duijn is an app developer and Master's candidate in Game & Media Technology at Utrecht University with eight years of hands-on experience building full-stack web and application features. She has shipped frontend-focused interfaces and backend services at companies from startups to enterprises, using React/Next.js, Go, C#, C++, Python and CI/CD tooling. Notable projects include implementing a drag-and-drop query builder and data visualizations, designing a feature-toggles backend, and leading frontend development and pipeline setup in cross-functional teams. Her background in creative technology and a year studying woodworking informs a unique maker mindset—she blends electronics (Arduinos, Raspberry Pi), natural materials and 3D modeling to build tech-infused art. Outside work she crafts wooden spoons, bakes bread, plays drums and hikes, which she says keeps her prototyping energy grounded and iterative. Based in Utrecht, she brings pragmatic engineering with a tactile, multidisciplinary approach to product development.
