Team Notes

What's Working Well ✅

  • Strong foundation: Provider abstraction enables multi-device support
  • Comprehensive testing: Mock providers keep CI green
  • Modern Android stack: Compose + Room + Kotlin best practices
  • Clear documentation: Week reports track progress effectively
  • Modular architecture: Easy to swap components (backends, providers)

Areas for Improvement 🔄

  • Hardware access: Need physical devices for realistic testing
  • Performance: Still above target latency (3-5s vs < 2s)
  • Deployment: Production setup not yet started
  • Load testing: Multi-user scenarios untested
  • Monitoring: Observability gaps in production

Blockers 🚫

  1. Hardware availability: Awaiting Meta Ray-Ban + OPPO Reno 12 access
  2. GPU resources: Backend optimization needs GPU for testing
  3. Network environment: Need production-like network for realistic tests
