Summary
👤
SeniorJesus Sanchez-palencia is a Core Systems Software Engineer with 17 years in the field and nine years focused on software engineering spanning embedded, mobile, and web systems. Based in the Greater Seattle Area and working at Facebook since 2018, he designs and implements low-level frameworks, bootloaders, hardware abstraction layers, drivers, and kernel-level components. He is fluent in C, C++, and Python and has deep GNU/Linux and OS expertise, having contributed to major open source projects like Qt, WebKit, Crosswalk, Contiki, Zephyr, and the Linux Kernel. His Contiki work highlights practical porting and driver development for Intel Galileo hardware—refining PIC, PIT, and RTC support—while his Crosswalk contributions improved extension messaging and runtime internals. Comfortable across front-end and back-end domains, he combines systems-level rigor with an ability to refactor and modernize large codebases. Colleagues rely on him for stable, performance-sensitive infrastructure that bridges embedded constraints and production-scale platforms.
