Hello and welcome !
Reunion Island being mostly francophone, I am pretty sure that you will have better chances of finding a job if you do your research in french.
I would suggest that you create your CV in the Jobs in Reunion Island section, make sure you tick the french translation and read the Guide de l'expatrié à La Réunion(which is in french) to gather as much information as possible.
Even when you apply for jobs, let's say on LinkedIn for example, better you apply in french (CV + Lettre de motivation)
