Les multiples chemins - Évolution de carrière

Parlons de ce qui angoisse la plupart des développeurs après 3-5 ans : “Et maintenant, je fais quoi ?” Parce que contrairement aux autres métiers avec des progressions linéaires prévisibles, notre industrie offre une multitude de chemins d’évolution, parfois déroutante.

J’ai mis 4 ans à comprendre qu’il n’y avait pas “un” chemin de carrière en développement, mais des dizaines de trajectoires possibles. Première leçon que j’ai apprise à mes dépens : vouloir suivre LE chemin “normal” peut vous mener dans une direction qui ne vous correspond pas.

Voici ce qui m’a pris trop de temps à réaliser : en 2025, les carrières tech les plus réussies sont celles qui combinent différents chemins plutôt que de suivre une voie unique et rigide.
