Description

I am passionate about new technologies and challenges!

For over 12 years in IT, I have worked with different languages, tried many tools and platforms.

My expertise remains around **JavaScript / TypeScript**: whether it's back-end (**NodeJS**), web (**React**), or mobile (**React Native**).

But by working with both startups and large corporations (LaCentrale, Pernod Ricard, KparK, Ubisoft, Hermès, TF1, VoyageSNCF / OuiSNCF, Les Mousquetaires, etc.), I understood that you always need to **adapt to the client's context, both at the company level and from a product perspective**.

Small budget, urgency, tight deadlines, many users, current product malfunctions, there are solutions for everything.

You just need to know how to look for them.

And I love finding them!

My philosophy is "**There are no problems; only solutions.**" (André Gide).

A brief overview of my background:

Back-end and mobile web development in NodeJS (Viadeo)
Native iOS development (PMU, LaCentrale, Pernot Ricard, Hermès, VoyageSNCF)
