## Pages

- [Home / About](https://ahronsilv.dev/): Overview, experience timeline, engineering toolkit, and contact details.
- [Case study — Native build engine for a multi-app fleet](https://ahronsilv.dev/work/native-build-engine/): A custom build-orchestration system that let five React Native apps share one owned native foundation — cutting per-app native config by ~98% (from ~1,890 lines across ~30 files to a ~30-line, 3-file glue layer) and roughly a week of native setup per app. Rebuilt across two generations: a bare-workflow foundation, then an Expo config-plugins wrapper that kept the same invariants.

## Selected open-source & public work

- [react-native-onesignal PR #1729](https://github.com/OneSignal/react-native-onesignal/pull/1729): Merged iOS native-bridge fix — a JS boolean was reaching Objective-C as an NSNumber instead of a BOOL, breaking the requestPermission fallbackToSettings path.
- [Severed Chains](https://github.com/Legend-of-Dragoon-Modding/Severed-Chains): Three merged Java PRs to a reverse-engineered Legend of Dragoon PC port — cutscene skips, fullscreen keybind, and GLFW mods support.
- [Shabbat Helper](https://github.com/ahronsilv/shabbat-helper): A Swift iOS app showing the closest candle-lighting time based on the user's location and timezone, using the Hebcal API.
