Back to original languageAbout Marc
I offer you my 15 years of experience in various innovative industrial projects and my expertise in real-time embedded systems and connected objects.
Formed in microelectronics on the technologies at the heart of electronic components, I first set out to explore the world of telecommunications and had the chance to be involved in the birth of the Internet of Things.
I then participated in the development of connected product lines with production runs of around 1000 units per year.
Through demonstrators, prototypes, test benches, or automated tools, I take great pleasure in implementing technology and interacting with its user.
My favorite discipline: low-level development where software and electronics meet to achieve the best performance criteria (resource sharing, real-time, energy consumption).
