About Julien

Passionate about new technologies and IT from a young age, I have had the chance to work as a developer for over 15 years.

I started as a PHP developer and then quickly moved to .NET, a language that has been with me daily since.

I have had the opportunity to work on APIs with significant technical challenges: security, performance, high volume, scalability, and it is on these aspects that I have built my expertise.

Throughout my career, I have held both developer and lead positions, which allows me to support the teams I work with in architecture, design, technical mentoring, and other aspects of product management.

Fond of code, I enjoy reading, writing, and discussing it, which is why clean code, refactoring, and maintainability are important to me.

As IT is a constantly evolving world, technological watch is essential for me.
