About Alexandre

Web DeveloperandMobilefor over **14 years**, I am currently available for missions in the following technologies:

💻Web Front-end Development**: **Vue**, **React**, and **Angular
🖥️Back-end Development**: **Node**, **Firebasesuite

On Capacitor/Ionic technologies, I can handle key aspects of hybrid development:updatesof native versions,addition and configuration of native plugins**, app redirects (**deeplinks**), **in-app purchases(with or without **RevenueCat**), **live updates**, etc.; in addition to classic front-end development.

I am also capable of working on back-end development (Node, Firebase).

→ I have worked for government agencies (**IGN** - National Institute of Geographic and Forest Information), large groups (**Suez**, **MAIF**, **France Télévisions**, **Alstom**), as well as smaller agencies (**Arpège**) or Start-ups (**Wino**, **Eatic**, **Hello Charly**).

→ I created these apps as side projects with Cordova or Capacitor mobile technologies, and Ionic:Bokha**, **Selfie AI**, **Luks AI**, **Oakly**, **Keeto**, **Just Breathe**, **Floral Escape**, and **Mooh(see portfolio).

→ I am also capable of working on projects using AI (whether it'sOpenAI**, **Anthropic**, **MistralAPIs or more complex topics). I have fully developed a website and an application for AI photo generation (gen AI - generative AI).

→ I have aScrum Master certification(PSM1) and am fluent in English (TOEIC score 945) and Spanish.
