About

Senior Android Engineer · Kotlin Multiplatform

Hi, I'm Eduardo Ruesta

I've spent over eight years building high-impact Android apps. In recent years I've focused on Kotlin Multiplatform and Compose Multiplatform, shipped apps on the App Store and Google Play, and I care about clean architecture, AI integration, and end-to-end product work. I bring experience from large teams (PayPal, Venmo, Despegar) alongside independent projects where I own architecture, backend, and store releases. I value maintainable code, well-integrated subscriptions, and experiences people use every day.

Featured projects

Three cross-platform apps I published on the App Store and Google Play — highlights from my independent KMP work.
