Full-Stack Mobile Developer
Native and cross-platform development focused on quality, performance, and user experience.
Experience with React Native, Swift, and Kotlin. I build back-ends with Spring Boot and other technologies, deploying to production environments such as AWS, App Store, and Google Play.
About Me
As a full-stack developer, I actively participate in every layer of a project —mobile, web, and back-end— with a strong focus on quality, performance, security, and continuous integration (CI/CD). I specialize in end-to-end project management, from requirements definition and client planning to deployment on AWS and publishing on the App Store and Google Play.
I've worked with and led development teams, driving effective solutions, promoting collaboration, and ensuring goals are met through Agile and Scrum methodologies. I possess an advanced level of technical comprehension and intermediate spoken English, allowing me to communicate effectively in international technical environments. This ensures organized, efficient, and high-quality development processes.
