About

Hi, I’m Diego. I’m an Android Developer with 7+ years of experience building large-scale consumer and business apps. I specialize in Kotlin, Android Jetpack, MVVM/Clean Architecture, and end-to-end delivery—from discovery and UX collaboration to release, monitoring, and iteration.

I thrive in cross-functional teams, delivering high-quality code and robust apps by coordinating with product, design, and QA. I enjoy turning feedback into tangible improvements that boost performance, reliability, and user experience across markets.
