Selected projects
SACADA
Sistema Aberto de Coleta Automática de Dados: a data acquisition platform for high-pressure physics experiments. Built using KiCad, STM32, C, and Python.
Autokit
An automated embedded Linux test framework developed at balena using TypeScript, with automation equipment prototyped in OnShape and on 3D printers.
Linux performance work
At Canonical, my kernel patches contributed to up to 32% faster performance and up to 18% less energy use on Intel Xeon Emerald Rapids.
Coverage in Phoronix / Linux kernel mailing list contributions
