About Me

Currently in my fourth year of engineering school, specializing in computer science at CESI Rouen, I am looking for a 12-week international internship from July to September 2026.

During my studies, I acquired a solid foundation in networking and systems, software programming, and web development. Since September 2024, I have been working part-time at the CESI research laboratory, on digital twin projects in virtual and augmented reality using the Unity game engine.

I have also completed several personal and academic projects, covering various areas of computer science. A selection of these projects, both completed during my studies and independently, is presented below.

2018 — Discovery of Computer Science

I became interested in computer science in 2018, with the ambition to create my own video game. This adventure began with the development of a 3D Snake game on Unity, a project that introduced me to the basics of game development in C#, and pushed me to learn 3D modeling with Blender.

2019 — Discovery of 3D Printing

In 2019, my passion for 3D modeling extended to 3D printing. I received a Creality Ender 3, which allowed me to bring my models to life and design objects with real practical use.

2020 — Electronics and Arduino

The year 2020 marked my first step into electronics. I designed and built a wooden safe controlled by Arduino, combining creativity, programming, and electronics. I also learned to use APIs to control LEDs via a web interface for home automation.

2021 — Olympiades des Sciences de l'Ingénieur

I participated in the Olympiades with my project PillHearth: an automatic connected pill dispenser. Built as a team of four in our free time, it earned us first place regionally and a national top 10 finish.

2022 — Entry to CESI

I joined CESI, an integrated preparatory school offering active project-based learning in teams — an approach that suits me perfectly, with the goal of pursuing a career in IT.

2022 — Discovery of Ethereum

2022 led me to discover Ethereum, a decentralized world computer. Fascinated by this technology, I dove into smart contracts and quickly learned to code in Solidity alongside my studies.

2022 — Web Development

After creating smart contracts, I wanted to build a user interface, which is how I learned to make websites with React — starting from traditional HTML, CSS, and JavaScript foundations. That's where my passion for web development was born.

April 2024 — Internship at CESI LINEACT

I completed a 4-month internship at my school's research laboratory, working on a Unity VR project developed in C# addressing the concept of digital twins.

September 2024 — Apprentice at CESI LINEACT

Following my internship, I continued working part-time at the CESI research laboratory as an apprentice, in parallel with my engineering studies. I contributed to the same Unity VR digital twin project, further strengthening my expertise in virtual and augmented reality development.
