Richard A. Perez

Android engineer. Kotlin, Jetpack Compose, and native modules when the UI stack is React Native.

I build production-shaped apps: camera/ML pipelines, BLE, OAuth/OIDC on mobile, and API-current Android (target 37). I also ship a long-running HTML5 card game, and I work in C# when the stack calls for it.

Looking at: Android roles first, React Native (I write the Kotlin side), then C# or JavaScript. Device/scanner/BLE work is a plus.

Start here

Repo Why it is here
LabelScanner React Native + CameraX + ML Kit. ROI, barcode/OCR, tests.
AnimeDB Compose, Hilt, Retrofit, MangaDex, clean architecture.
OAuthOpenID Real PKCE + Custom Tabs + ID-token checks.
JS_team_poker Playable HTML5/JS game.
CardWar Compose rewrite of a legacy Java game.
ApiUpgrade37 Runnable catalog of Android 17 / API 37.

Also: Workoutapp (BLE), JetpackSecurityAPI37, FinnStock (MVI), ColorTimerMaui (C# / .NET MAUI).
