Back to original languageAbout Thierry
My company, Linatsea (as in "Linux at Sea"), supports its clients with embedded Linux and microcontroller needs, real-time issues, performance optimization, as well as developer training, and aims to address projects related to the maritime world.
After more than four years in business, I have worked on topics such as secure over-the-air (OTA) updates, BSP and driver porting, industrializing Linux boards, and microcontroller power consumption... with a majority of clients in Brittany who are involved in maritime activities (offshore racing, underwater drones, ...).
In addition to my 25 years of expertise in Linux-based embedded systems, I also master Zephyr RTOS (Device Tree, Power Management) and have completed several projects implementing its BLE stack, as well as its OTA system.
With my dual software/hardware expertise, I can assist clients in the design and development of their electronic board prototypes.
Oscilloscopes, logic analyzers, power profilers, and micro-soldering equipment are part of my toolkit.
