About Jean-Christophe

With over 15 years of experience in backend development and several years of frontend experience, I anticipate scalability and volume issues and deliver maintainable code.

I worked for a long time in the Java ecosystem. I am now focused on the Node.js ecosystem with TypeScript.

I have held tech lead positions, trained junior developers on several missions, and architected complex systems.

I have worked in companies of all sizes, from startups (Voggt) to financial institutions (SGCIB, Amundi), including medium-sized companies (AEP, AAVA).

Furthermore, I am a proponent of agility, quality code, and I emphasize maintainability.

My strength lies in promoting code quality while remaining pragmatic for the benefit of the projects.

I use AI in my daily work to increase my efficiency, while maintaining control over what I produce.
