Ángel Ballesteros Arribas

Android mobile application developer with 10 years of experience. I have worked both within teams and individually as a freelancer, traveling to client offices or working remotely. During this time, I have carried out complete projects from scratch and also projects with problems or in mid-development to complete them or fix errors.

Experience also in the development of multiplatform native applications (Android and iOS) using the Flutter and Kotlin Multiplatform Mobile frameworks.

I develop both the native Android application and the backend for it, either on platforms such as Firebase together with nosql databases or designing more classic own servers in PHP-Mysql or Kotlin.

I like to keep up with the latest trends in mobile development, implementing clean code architectures and Material Design with MVVM design patterns, and using widely used libraries such as Retrofit, Room, Hilt/Koin, Jetpack Compose, etc., to facilitate scaling and correct maintenance of applications.

I have carried out five online teaching sessions (preparation of the syllabus, streaming tutorials, planning and correction of exercises...), of the Android Development module within a Diploma in Mobile Application Development in Spain, Colombia and Panama.

I also have 4 years of experience in the development of C++/C#/Windows desktop applications in highly complex multi-machine and multi-threaded processes, working at a low level of abstraction and prioritizing algorithms and efficiency.

Count on me if you are looking for a reliable person whose greatest interest is that you are 100% satisfied with the final product, without fear of making the modifications that are necessary to achieve it.
