Summary
👤
Senior🎓
Top SchoolJecel De Assumpção is a software engineer and chip designer with deep roots in both computing research and aeronautics, combining academic rigor with entrepreneurial experience. He has decades of hands-on work designing Smalltalk-based computers and custom microprocessors, having run companies that built educational machines and Motorola 680x0-based systems. His research roles at Universidade de São Paulo focused on parallel machines and low-cost graphical workstations, and he has taught advanced networking topics at PUC-SP, even authoring a course book. Equally comfortable in system programming, IC design, and programming language design, he bridges hardware and software in uncommon ways. Based in São Carlos, Brazil, he brings a practical history of shipping bespoke computing platforms for education and research. A lesser-known fact: his Smalltalk computer designs date back to the 1980s, reflecting a rare, long-term commitment to integrated hardware/software systems.
