• Magna instrument Firmware development (2020-2023) - Depixus, Paris

Depixus is a biotech company developing a new technology (MAGNA) for extracting advanced information from DNA/RNA fragments. Because the technology is unique, the company developed in-house a specific instrument to support it.

I contributed to this project by having the responsibility of developing the instrument firmware, which pilots most of its physical functions. Initially, I spearheaded the project independently, and later, two junior engineers joined the team under my supervision. Through collaborative efforts with other departments such as Mechanical, Electronics, and R&D, we successfully engineered a robust firmware that is now deployed on the Beta release of the instrument.

Throughout the project, my responsibilities included:

• Selecting the appropriate microcontroller model and contributing to its integration onto a printed circuit board (PCB).
• Designing and implementing an architecture based on the Active Objects pattern using the QPCPP framework suite
• Developing drivers and middleware in C and C++ for various components including IMU, Motors driver (Stepper, DC), position sensor, external ADC, RH sensor, EEPROMs, screen controller, laser controller, and temperature sensor.
• Developing numerous unit and integration tests for the active objects, drivers, and middlewares
• Creating docker images and CI pipelines on GitLab for running unit tests on the cloud and integration test on dedicated testbenches
• Implementing Scrum and DevOps methodologies within our team of three engineers, where I took on the roles of both product owner and developer.
