Description

A software engineer by training, I transitioned to web and mobile development in 2019. Since then, I have developed and delivered several Android and iOS mobile applications in React Native across various sectors: foodtech, connected health, transport, telecommunications, and media/connected TV.

I have worked on greenfield projects, high-traffic applications, and native and hardware integrations (Bluetooth, USB, in-app payments, authentication). I also master modern best practices: TypeScript, GraphQL, automated testing, CI/CD with Bitrise/Github, Storybook.

Today, I am open to React Native mobile developer roles, ready to engage in ambitious and complex projects, collaborating with multidisciplinary teams.
