Cross-Platform Developer

About me

Over 14 years of experience in software development, 5 years working with cross-platform application development for IOS and Android using the React Native framework, and more recently Flutter.

Working remotely full-time for about two years.


Experience in the development of transport and delivery and management applications, with real-time functionality, and persistence of offline data using mobile-first concepts and standards.

My last works focused on the medical field, with applications for managing patients and health professionals.


I work from the architecture and design of the app, using engineering and design standards such as SOLID and ATOMIC DESIGN, which provide better reading, ease of maintenance, and clean code.

Because of my constant relationship with great UX and Design professionals, I ended up absorbing a little knowledge in this area, today I can design screens and wireframes (using SKETCH and ADOBE XD), define user journeys within the app and think about each functionality so that the user gets the best experience.
