With a Master's degree in "Software Science and Engineering" and a robust mathematical foundation, I've made significant contributions as a software engineer within a distinguished research laboratory affiliated with the CNRS (French National Center for Scientific Research). Transitioning to Luxembourg, I initially joined a premier IT consulting firm, focusing on serving one of the top 5 banks in the country. Upon being approached by Datathings, I was captivated by the potential of their product, the GreyCat Database, prompting my decision to join them as a core systems engineer to actively contribute to its development.

Software Engineer (Apprenticeship)
ICube laboratory of research, Strasbourg (Aug. 2021 – Sept. 2023)

Technical stack: Java 11/17, Spring Framework (Spring boot, Spring Data, Spring Security, Spring MVC), Maven, Restful API, gRPC, Websocket, Protobuf, Python, NodeJS, Oracle Database, Redis, Hibernate, GDal, Git

During my tenure as a member of the data science research team at ICube laboratory of research in Strasbourg, I played a key role in the development and management of a data mining platform tailored for remote sensing applications. My responsibilities encompassed implementing new features, addressing anomalies, and formulating architectural proposals to enhance the overall efficiency of the platform. I collaborated closely with fellow researchers in our daily activities.

Furthermore, a significant aspect of my role involved overseeing and guiding interns in their learning process. This experience allowed me to contribute to the growth of the team and foster a collaborative and productive work environment.

Master’s thesis project Jan. 2023 to June. 2023

In collaboration with three other colleagues, we built a generative-AI based tool called Beat-Pix that creates videos based on input music. During this project, we trained the MusCap model referenced in this paper and fine-tuned the LLaMA and Stable Diffusion models to generate coherent videos matching the input music. We believe this project is meaningful as it could assist people with hearing difficulties in understanding the content and emotion of music.
