Background

Passionate about web development and technologies, I started my career as a graphic designer before reorienting myself towards full-stack development.


With notable experience in printing where I acquired solid skills in visual design and preparation of files for printing, I decided to evolve my career towards programming and digital innovation.


After intensive training at the Holberton School, I specialized in web and mobile web development. I completed my RNCP Level 6 (Application Designer Developer) diploma through a work-study program at IT&YOU in Lille, where I now work as a full-stack developer.


At IT&YOU, I designed and built a full CRM / ERP suite from the ground up, covering prospect portfolios, commercial projects, client management, stock, contracts, technical interventions, after-sales service, and accounting tools. Alongside this role, I continue to design and ship band websites that blend strong visual identity with performant front ends.


My background demonstrates a unique combination of creativity, technical rigor, and the ability to deliver quality solutions in agile environments.


Education

• RNCP 6 (BAC +4) - Application Designer Developer
Holberton School & IT&YOU, Lille, France (2025 - 2026)

Completed as a work-study program at IT&YOU, this diploma deepened my ability to analyse business needs, design scalable applications, and deliver production-ready software. The curriculum combined advanced full-stack development with real-world delivery on a company-wide CRM / ERP platform, from architecture and implementation to testing, documentation, and continuous deployment.






• RNCP 5 (BAC +3) - Web Developer & Mobile Web Developer
Holberton School, Tourcoing, France (2024)

This intensive, project-based program provided in-depth training in both web and mobile development, focusing on modern programming languages, frameworks, and best practices. The curriculum was built on a unique learning model that prioritizes self-directed learning, autonomy, and initiative. With a focus on real-world challenges, I gained hands-on experience in software design, continuous integration and deployment, agile methodologies, and effective debugging techniques.

Collaboration was at the core of the program, where peer learning and teamwork were emphasized through daily group projects and code reviews. The program also offered substantial exposure to problem-solving in complex environments and adapting to new technologies rapidly. By the end of the course, I was well-equipped to tackle both frontend and backend development, and thrive in dynamic, fast-paced team settings.






• Bachelor in Digital Arts
Academy of Fine Arts of Tournai, Belgium (September 2010 - June 2014)

During my time at the Beaux-Arts de Tournai, I studied a diverse range of creative disciplines within the field of Digital Arts, focusing on mastering techniques in video production, graphic design, photo editing, and photography. The program provided a strong foundation in both the technical and artistic aspects of these media, with a consistent emphasis on using advanced digital tools.

This experience not only developed my technical skills but also allowed me to refine my creative process, from concept to execution, whether working independently or in collaborative environments.
