Tuan Ha en quelques mots
Je suis développeur Java - Springboot depuis 2012. J'ai travaillé pour les grandes boîtes en interne : Amadeus, Traveldoo-Expedia, Oui SNCF, Rakuten Advertising où j'ai pu acquérir et maitriser mes compétences en développement application Backend ainsi que sur le cloud comme pour Google Cloud Platform.
Je pourrais faire des propositions architectures et faire des POCs très rapid qui vous permettre de débuter un projet en très peu de temps (Springboot, GCP comme Google App Engine, Google K8s, etc.)
Si vous avez des questions, ou besoin plus de précision sur moi, ou pour le CV, n'hésitez pas à me contacter
A très bientôt
