About Julien

Graduated since 2012 but passionate for even longer about computer development, I make my skills available to provide pragmatic solutions to your problems.

I design, develop and maintain web and mobile applications with an approach:

- Functional: aligning the code with business needs, particularly through Domain Driven Design,
- Quality: relying on the SOLID, DRY, KISS principles and the implementation of tests, continuous integration and documentation,
- Maintainability: with the use of architectures and patterns allowing the scalability of applications such as Clean Architecture and CQRS.

This approach adapts according to the constraints and needs of the project as well as the team with which I am working.

Aware that tools and technologies are evolving rapidly, I place particular importance on technological monitoring as well as improving my practice through experiments and personal projects that I share on my blog or my Github profile.
