Senior Mobile & FullStack Developer

Building the future, one app at a time

Mobile developer with more than 5 years of experience building native applications (Kotlin, Swift) and cross-platform apps (React Native, Flutter), focused on performance, clean architecture, and excellent user experience. I have led and collaborated on mobile projects integrating backend (Node.js, Laravel), databases (MySQL, Firebase), and cloud deployment (AWS, NGINX). Additionally, I have solid knowledge in frontend with React and development best practices such as GitFlow, version control, and agile methodologies (Scrum).
