J’ai eu l’occasion de collaborer avec Joffrey pour la remise à jour d'un site WP non maintenu depuis 7 ans et je recommande vivement ses services.
Il a fait preuve d’une excellente compétence technique, d’une réelle capacité d’initiative et de proposition, ainsi que d’une grande autonomie, y compris dans des délais très resserrés. Ses explications étaient claires et pédagogiques, ce qui a grandement facilité la collaboration. J’ai particulièrement apprécié sa réactivité tout au long de la mission ainsi que le suivi post-mission, qualitatif et toujours disponible.
Bref, un prestataire de confiance sur qui l’on peut s’appuyer sereinement.
