Apps that hold up after launch
-
Cross-platform apps
iOS and Android from one Flutter codebase, published to both stores.
-
Clean architecture
I refactor legacy apps with SOLID principles so teams can keep shipping without breaking things.
-
Offline and sync
Apps that keep working without a connection and sync when it returns, like the Filup Check kiosk.
About
Hi, I'm Roger!
I'm a mobile engineer who enjoys a hard problem and keeps learning. I apply best practices on every project so the code stays clean, efficient and scalable, and I care just as much about how the app feels to the people using it. I studied Computer Science at UADY and work in Spanish and English (C1).
