Freelancer profile translated to English.

Description

Software developer trained at École 42, with practical experience in TypeScript environments and web and mobile development.

I have worked on applications in Angular and Node.js in Agile teams, and I led a complete personal project in React Native and Expo, including multilingual support, in-app purchases, and store publication.

Solid foundation in C, C++, Docker, CI/CD, and modular architectures. I prioritize code quality, maintainability, and the industrialization of application environments.

I assist companies in the design, development, and evolution of their web and mobile applications, with an approach focused on quality, performance, and continuous delivery.

Responsive, autonomous, and solution-oriented, I work on both new projects and technical overhauls requiring rigor and efficiency.
