We help media companies, game studios, and digital agencies migrate and build applications for Amazon Vega OS (Fire TV) and React Native Multi-TV platforms:
- Fire OS to Vega OS Migration & Multi-TV Monorepos: Porting existing Android/Fire OS and React applications to React Native for Vega (0.83 / Vega SDK 0.24) and shared Multi-TV architectures (Fire TV, Android TV, tvOS, Web).
- 10-Foot UI, Performance & Accessibility: Non-blocking background computation via Hermes worklet runtimes (
@amazon-devices/react-native-worklets) and MMKV state bridges, deterministic D-pad spatial navigation,useKeplerBackHandlerlifecycle handling, and full VoiceView screen-reader compliance for Amazon Appstore certification. - Automated Device Verification & AI Tooling: Scriptable testing, frame/audio capture, and CI/CD verification on the Vega Virtual Device and physical Fire TV hardware using our open-source
vega-vvd-driverandproofgate.
