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.
