As a system engineer at Alstom, I was able to take part of the development of the new CBTC system named Urbalis Fluence. It was waiting to be deployed in Shenzen's subway, line 20, in China.

Fluence is able to leverage train-to-train communication to increase the throughput of the line compared to previous automated subway technologies such as Urbalis U400.

I participated in the control design in collaboration with system architects, establishing behavior of the trains and the devices on the network.

I presented the new system features to the software team in order to explain how these would work and discuss potential development issues.

I also managed traceability and refinement with high-level requirements with the signalling team as well as testing and satisfaction with the verification and validation team.

As a hardware security engineer at the Syst├¿mes et Architectures S├®curis├®s laboratory of Mines St-Etienne, I was able to develop SCABox, an opne-source test bench that evaluates the resilience of crypto-algorithms during side-channel attacks. The project is available on GitHub.

The bench provides FPGA power sensors that can be implemented on a remote fabric. It can perform attacks on the electronic board where it is located and communicate results to a client computer. It succeeded in breaking the encryption key used by the famous OpenSSL's AES algorithm.

I worked in collaboration with a research team that helped me to understand the side-channel attacks fundamentals and provided me with a proof of concept code.

I autonomously developed the test bench architecture, composed of the power sensor, a demo hardware AES to attack and interfacing with the CPU of the development board.

I also developed a low-level driver application that runs on the board and can both receive control attack triggering and transmit power leakage via serial link.

I developed the remote client application that was able to communicate with the driver and gather power leakages from the fabric to visualize these and break the encryption keys via statistical measurement.

I provided the solution with a documentation website featuring getting started guide and explanations on how the bench works.

In the context of an academic project at Mines-St Etienne, I was able to contribute to the development of a validation bench for a microscope manufactured by the company xRapid to perform medical analysis.

The validation bench performed a quality GO/NO GO test at the output of the microscope production facilities located in China.

I worked in a team of three engineering students during the, autonomous during the whole project,

We established establishing the quality requirements, budget and planning, with xRapid.

I participated in the development of the iOs application that paired with the microscope, using Bluetooth, to perform the test.

I was mainly in charge of the software architecture, ensuring quality and maintainability of the different software parts.

I also designed and developed the graphical user interface of the application as well as a displacement detection algorithm for the microscope's stage based on OCR technology.

As a student at Mines St-Etienne, I committed myself into several projects, in order to enhance my abilities in software development as well as to get introduced into scientific topics that interested me. Most of these projects are available on GitHub.

I followed online lectures, especially from MIT OpenCourseWare, In order to get deep into materials relation to my engineering graduation such as cryptography or algorithmic and data structures but also to get introduced to new programming languages and skills.

I also followed various lectures on scientific topics such as computer graphics, image processing or differential geometry when it was required by the projects I was working on. Sometimes I was also brought into reading academic papers

I developed most of the software projects using continuous integration and following agile development guidelines. Some of these are publicly available on package mangers such as npm and have more than 1000 downloads.

As a student at Mines St-Etienne, I had the occasion to acquire advanced scientific knowledge, develop technical skills as well as project and business management skills.

Mines-St Etienne is one of the top ten French engineering school, emphasizing on projects and multidisciplinary to provide a holistic view of the role of the engineer.

I had the occasion to get introduced to both electronics, embedded systems and computer science. This provides me a technical tool box to understand the behavior and architecture of computers and embedded systems.

I decided to major in microelectronics design, learning in 6 months how to design integrated circuits such as ASIC and how to perform prototyping using FPGA. I was also introduced to the semi-conductor physics and manufacturing.

I minored in information technology and supply chain, learning about operational research, especially optimization using CPLEX.
