Hello. I’m Gabriel

Android consultant helping companies make solutions led by user focused engineering. Mission: "CEO should concentrate on a business, I'll take care of the software."

Portfolio

For over the past six years, I've worked as a developer specializing in Android software. I communicate extremely well and have been a part of various-sized teams. In my career, I've worked on multi-million user apps and am passionate about good development processes and know how to foster them. I prefer Kotlin over Java and Flutter over Kotlin. Lately, I've been immersing myself into AR/VR, 3D, and even 4D projects.
