Rockstar🎓
Top SchoolGeoffrey Prewett is a Senior Software Engineer with nine years of professional experience (and two decades of broader engineering work) who specializes in user interfaces, graphics, and cross-platform apps with a particular affinity for making tools feel "magical" and joyful to use. He has shipped desktop, mobile, and web solutions—from iOS apps and games to high-performance 3D viewers and visualization tooling—combining C++, OpenGL, Swift/Objective-C, WebGL, and Python. Geoffrey has contributed notable features to the Open3D ecosystem (adding vertex selection and advanced visualization/shader support) and built practical production systems like job-shop scheduling and engraving integrations at RTIC Outdoors. As a founder of Eight Brains Studios he designed and marketed consumer-facing mobile apps that blend UI polish with technical depth, and his freelance work spans projection editors, BIM viewers, and accessibility-driven text tools. Based in Redding, CA, he pairs systems-level engineering and tooling experience with a designer’s sensibility for interaction, often solving tricky visualization and UX problems that make complex data approachable.
