Challenge
Decima’s development involved complex challenges across AI integration, health data synchronization, compliance enforcement, and personalization at scale.
- AI System Integration:
Combining Whisper STT, ElevenLabs TTS, and LLMs demanded flawless real-time processing, especially for consistent persona-driven interactions amid network variability.
- Health Data Syncing:
Continuous Apple HealthKit integration for sleep, activity, and biometrics required real-time normalization and advanced algorithms to generate composite health scores from inconsistent data.
- Protocol Compliance:
The platform enforced proprietary health protocols across billions of recommendation combinations. Preventing hallucinations in LLM outputs required strict prompt engineering and filtering.
- Persona Management:
The admin interface supported on-demand persona creation, real-time updates, A/B testing, and behavioral customization — demanding innovative architecture for instant synchronization.
- Adaptive Scheduling:
Tasks were dynamically generated from user data and synced with Apple Calendar, adapting based on task completion tracked via PostgreSQL to match user capability and progress.
- Content Personalization:
Keywords extracted from chats guided Feedly-based content recommendations. Cron jobs and relevance scoring ensured alignment with users’ evolving health goals.
