About Franck

10 years of experience have taught me that a good application is not just a collection of features, but a solid foundation capable of evolving without pain.

Expert in the JavaScript/TypeScript ecosystem, I navigate with equal ease through Frontend frameworks (React, Angular, Vue) and complex Backend architectures via NestJS. My Cloud expertise (AWS/GCP) allows me to guarantee the total availability of your services.

I am also ready to commit to an AI Engineer position, including on "junior" issues specific to this field. My goal is to combine my solid mastery of Fullstack development with rapid skill acquisition on your AI models and technologies.

Let's discuss your technical challenges to see how I can help you overcome them.
