Android & iOS Mobile Developer

Quick facts

¹ at the time of writing.

Summary

I got a five-years Bachelor's degree in Computer Science in 2006. Since then I am working as a consultant for private corporations providing software development in fields such as finance, telecommunications, mass retail and medical.

I've been developing mobile Apps for ten years and more. I work fully remotely since 2018, now at Playtomic as an Android and iOS native Mobile developer. During my career, I have been involved in a wide spectrum of software projects ranging from firmware development to back-end development sometimes as a Team Leader.

Beside my general interests in programming languages, I follow with enthusiasm Kotlin/Native and its use in Multiplatform projects. I remain focused onto the evolution of the best practices in the field of software architecture, for which I have empirically developed the belief that Clean Architecture is always desirable at the application level.

I have experience with different programming paradigms (Object Oriented/Functional/Logical), specializing with on device Digital Payments protocols, nowadays offered through Host-based Card Emulation of Type 4 tags by Apple Pay and Google Pay and in the automation of software life cycle processes.
