ABOUT ME
Swift developer with more than 12 years of experience
Swift developer with more than 12 years of experience

I am a staff software engineer focused on mobile (iOS) and games, with more than twelve years of experience, twenty published applications on App Store and seven launched games. I had my game studio for a long time with some partners, Funbites Game Studio, where I could win four awards of national recognition.

I have a massive experience with Swift and Objective-C language and excellent knowledge of the best coding practices like project patterns, clean architecture, clean code, and all kinds of tests (Unit, UI, and Snapshot). Currently, I am working as an iOS Engineer at Riot Games (by Xteam) on a native iOS project.

I've worked with many technologies on my journey, and I am passionate by facing challenges. For me the technology gives us the possibility to impact the world in a good way. I am a speaker, influential, and engaged with the technology community! I create content for the Attekita Dev channel (YT and Instagram), which impacts more than 100 thousand people.
