What I'm looking for

Seeking opportunities to build scalable mobile applications, lead teams, and work with modern technologies to drive innovation and deliver exceptional user experiences.

As a seasoned React Native Developer with 8 years of experience, I specialize in building scalable and high-performance mobile applications. My expertise includes React Native, TypeScript, and GraphQL, with a strong focus on best practices like SOLID and clean code. I have successfully led a team of 6 developers as a Tech Lead, driving technical strategy and execution to deliver impactful solutions.

In my current role at Z1, I have developed and maintained core features, led the redesign of the Design System, and improved performance and UX. I also built a web interface with React and Next.js for Open Finance integration. My experience extends to structuring educational content as a React Native Instructor at Alura, where I created courses and resources to help others grow in the field.

My journey includes contributions to various projects, from mobile game development to full-stack and web development. I am passionate about fostering team engagement and ensuring reliable testing with tools like Jest and Detox. I am committed to continuous improvement and leveraging modern technologies to create efficient and user-friendly applications.
