About me

I'm a second-year student of the Higher Technician in Data Science and Artificial Intelligence (two out of three years) with hands-on experience in Linux server administration, application deployment, and backend development. I'm interested in the intersection between data analysis and software engineering: not just building models, but deploying and maintaining them in production.

Beyond my technical background, I work as a teaching assistant at university — an experience that sharpened my ability to communicate technical concepts clearly and empathetically. I am looking for a first formal professional role where I can contribute real solutions and keep growing within a team.
