Mandate
Design, build, and operate Nomino, a voice-first iOS 26 app that pairs SwiftUI with LiveKit and Google Vertex AI Gemini 2.0 Flash for conversational language practice. The focus: realtime reliability, privacy-first data controls, and a polished Liquid Glass experience for every beta cohort.
Core responsibilities
- SwiftUI + UnifiedDS Liquid Glass architecture with SwiftData state persistence and BGTaskScheduler automation.
- LiveKit SDK session orchestration for bidirectional audio, data-channel RPC, and realtime transcription.
- Vertex AI Gemini 2.0 Flash prompting, multilingual translation, and text-to-speech voice responses.
- Crash analytics, Mixpanel telemetry, and full TestFlight cohort operations and support cadence.
What I maintain week-to-week
- Automated build and TestFlight distribution via Fastlane + GitHub Actions with release QA gates.
- LiveKit Cloud monitoring, latency benchmarks, and Gemini prompt evaluations before weekly pushes.
- SwiftData migrations, GDPR-compliant retention policies, and VoiceOver/Reduce Motion accessibility audits.
Recent outcomes
- Introduced offline lesson caching that reduced abandonment by 19%.
- Deployed sentiment-adaptive prompts, increasing conversation length by 27%.
- Featuring Nomino in community showcases, driving 120 new testers in two weeks.
