Senior🎓
Top SchoolGuilherme Hazan is a senior software developer with over 30 years of hands-on experience in systems programming, UI components, and mobile/embedded platforms, currently based in Stuttgart. He architected and implemented from scratch a mobile/desktop Java virtual machine (inspired by Dalvik) and three distinct garbage collectors as part of his Master's thesis, producing an API of 150+ classes used worldwide. Fluent in C, C++ and Java, he has delivered production software across Palm OS, BlackBerry, iOS, Android, Windows CE/Phone and Brazilian DTV set-top boxes, and he continues building cross-platform solutions through his companies and projects. Founder of multiple ventures including SuperWaba and TotalCross, he blends entrepreneurial grit with deep optimization and performance expertise. Known for a lifelong passion for code—starting on an Apple II in 1984—he also brings international perspective from time living in the U.S. and a recent move to Germany. Practical, performance-driven, and curious, he often tackles low-level challenges that most application developers avoid.
