About Kévin

I am a React Native developer, specializing in creating modern, fluid, and reliable mobile applications with clean, structured, and maintainable code thanks to TypeScript.

Tech stack:
- React Native (TypeScript), Zustand, Reanimated v3, React Native Paper
- API integration with Axios
- Node.js, Express, and Prisma Backend
- PostgreSQL, MySQL, and MariaDB Databases
- Deployment and server management on Debian (Nginx, PM2)

I have a strong foundation in web development (HTML, CSS, JavaScript), which allows me to write clear and coherent code and ensure a fluid user experience on both iOS and Android.

Before diving into mobile development, I designed and developed a complete framework for a FiveM server, managing server logic in Lua and Node.js, as well as the client-side in Lua, HTML, CSS, and JavaScript. The project hosted between 90 and 130 simultaneous players each evening, which taught me to optimize real-time systems, manage performance, and maintain a stable architecture under load.

I also served in the Army as an escort and convoy protection operator. This experience instilled discipline, rigor, and composure, qualities I apply in my work today.

If you are looking for a developer capable of transforming an idea into a reliable, modern, and scalable mobile application, I am available to collaborate with you.
