Back to original languageAbout Rafael
I am a Computer Engineer specializing in the development of applications for iOS and Android.
My main focus is on creating native iOS applications using Swift 6.0 and SwiftUI, as well as Android applications using Kotlin or Java.
I have been developing Apps for companies since 2014. Some of my clients include: Atresmedia, companies from Dubai and Ireland, international banks, insurance companies, city councils, and universities.
In addition to working with clients, I also dedicate time to my own startup projects, creating ventures with the potential for success. With my Apps, I have over 5 million downloads on Android and 500K on iOS.
Some highlights of my technical skills include:
- Implementation of architectures such as MVP, MVVM, VIPER, among others.
- Application of SOLID principles.
- Experience in agile methodologies like SCRUM.
- Development of unit tests.
- Version control with GIT: Github, Bitbucket, and Gitlab with SourceTree.
- Code analysis: Swiftlint, SonarCloud.
- Project management with: Jira, Confluence, Slack.
- Version delivery: Testflight, Play Store, App Center, Applivery.
- Designs in Figma, Zeplin, and Moqups.
To do a great job, you have to love the work you do, and I don't just like it, I'm passionate about it!
