About Julien

Software engineer and full-stack developer jack-of-all-trades, I started coding as a teenager and never abandoned this passion, whether professionally or for personal and open-source projects.

My passion: systems development and web development, well-crafted software architecture, and video game development to which I dedicated part of my career.


I have worked as an employee and as a freelancer in the video game industry, and developed various web and system tools to support them, as well as provided web services for external clients in parallel. This is how I became familiar with front-end and back-end web development after general engineering studies focused on IT and software engineering.


I have also had the opportunity to work extensively in education, giving various courses on software development, from VueJS development to Desktop development, including development on major video game engines and embedded development on microcontrollers, depending on the course opportunities entrusted to me. Through this experience, I also developed a complete web tool to assist me in grading and distributing evaluation feedback, Tardigrade, whose back-end is entirely in Rust and front-end in LitElement, as well as its integrated and lightweight database, reindeer-rs, also written in Rust.

I am available for development or consulting missions, alongside my intermittent involvement in education, which remains a definite passion.
