About Me

I'm a Frontend developer specialized in web and mobile applications with React and React Native, focused on creating robust, scalable and maintainable products in real production environments.

Throughout my experience I have worked on complex projects from the initial phase to production, participating in technical decisions, performance optimization and continuous product improvement.

I am characterized by being consistent, responsible and focused on code quality. I enjoy collaborating in agile teams, solving real problems and building solutions that add long-term value.

Currently open to remote or hybrid opportunities in product and technology environments.
