Senior Mobile Frontend Engineer at Myka · Nairobi, Kenya · UTC+3
I build the layer where JavaScript meets the device — the seam where a feature stops being a screen and becomes a camera pipeline, a background task, or a native module. Nine years of frontend, most of it spent making hard things sit behind small APIs.

React Native modules for iOS and Android, written in TypeScript over Kotlin and Swift.
| Package | |
|---|---|
| react-native-liveness | Liveness detection built on Vision Camera v4 and ML Kit, with frame-level quality gating so a bad capture fails fast instead of failing late. |
| react-native-face-verify | Compares a reference image against a live front-camera capture — ML Kit and AWS Rekognition out of the box, or point it at your own endpoint. |
| react-native-lottie-splash | An animated Lottie splash that plays on launch and dismisses on cue, with none of the white flash that usually sits between the two. |
| react-native-developer-mode | Detects whether developer mode is enabled on Android and iOS, for apps that have a reason to care. |
All four are on npm under @rick427.

Code is like humor. When you have to explain it, it's bad.
