Summary
🤩
Rockstar🎓
Top SchoolAurelien Jarno is a seasoned computer engineer with 26 years of experience combining embedded systems, low-level Linux internals and scientific research at the Centre de Recherche Astrophysique de Lyon. He holds a PhD in optics and image processing from INSA Lyon and brings deep hands-on expertise in RTOS and microcontroller work (Zephyr/STM32) alongside kernel and libc contributions that improve stability and performance on x86 and RISC‑V. An active Debian developer and long‑standing open-source contributor, his patches range from USB utilities parsing fixes to critical glibc ABI and stack-alignment bug fixes—work that quietly reinforces core tooling many projects depend on. Equally comfortable with GPIO-driven embedded features and subtle endianness/build fixes, he has a knack for finding small correctness issues that prevent hard-to-reproduce failures.

gregkh/usbutils
Apr 2009 - Jan 2021
USB utilities for Linux, including lsusb
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 review, 14 commits, 8 PRs in 11 years 10 months
Contributions summary:Aurelien contributed to the `usbutils` project by fixing bugs and improving code quality. Their work primarily involved fixing parsing issues in `lsusb` related to handling of USB device information from `/proc/bus/usb/devices` and correcting endianness. They also addressed a typo and added a missing include file. These modifications indicate a focus on maintaining the correctness and reliability of the USB utilities.

zephyrproject-rtos/zephyr
May 2018 - Sep 2024
Primary Git Repository for the Zephyr Project. Zephyr is a new generation, scalable, optimized, secure RTOS for multiple hardware architectures.
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:134 reviews, 189 PRs, 893 comments in 6 years 5 months
Contributions summary:Aurelien made several contributions focused on enhancing the Zephyr RTOS for embedded systems, specifically targeting STM32 microcontrollers. Their work involved adding support for reading the EUI64 ID on STM32W* devices, implementing shell commands to display this ID, and optimizing existing code by removing floating-point computations to save flash memory. Furthermore, they addressed various issues, including fixing pylint issues in scripts, adjusting SPI frequencies, and adding support for the MSI clock on STM32WL.
