Rockstar🎓
Top SchoolGeorge Hilliard is a software engineer with 13 years of experience building machine-learning silicon, high-performance chip firmware, and embedded Linux systems, currently working at AWS in Austin. He combines deep hardware knowledge—PLL/clocking work in the LiteX ecosystem and firmware leadership at Kopis Mobile—with pragmatic embedded Linux expertise demonstrated by a Buildroot business-card Linux and U-Boot/device-tree contributions. His open-source footprint spans tooling to apps, from improving RawTherapee’s batch queue robustness to optimizing Z80 calculator OS routines, reflecting a focus on reliability and low-level performance. George is passionate about free software and Linux, and brings hobbies as varied as amateur photography and mechanical tinkering that inform a meticulous, systems-level approach to engineering. Not obvious from titles alone, he has a track record of squeezing constrained platforms for full functionality—writable root filesystems, USB gadget support, and careful PLL feedback handling—making him equally at home in silicon, firmware, and system software.

OS for z80 calculators
Role in this project:Embedded Systems Engineer
Embedded Systems EngineerContributions:34 commits, 3 comments in 1 year 5 months
Contributions summary:George primarily contributed to the OS for z80 calculators by implementing and optimizing core system functionalities. Their work included documenting and implementing file stream routines, such as reading and writing to streams, and fixing a time string in the "Castle" application. They also implemented a radix sort algorithm and made various style and usability improvements to it. Furthermore, the user added a message display function to the applib library, addressing a specific issue, and improved the terminal interface.
