Cross-Platform AI Personal Assistant

KnappIT is building a full-featured AI assistant (Lity). I need someone who can take the idea from concept to a polished product that works seamlessly on iOS, Android, and the web.

The assistant must handle both voice and text interactions fluidly: think high-quality speech recognition, natural-sounding TTS, and a chat interface that keeps context across devices. You’ll architect the back-end intelligence and then wire it to native mobile front-ends plus a responsive web app.

Key deliverables
• A scalable back-end (Python, Node, or comparable) exposing clean APIs for voice/text queries
• Mobile clients for iOS (Swift/SwiftUI or React Native) and Android (Kotlin or React Native) plus a browser-based interface
• On-device wake-word or tap-to-talk, real-time STT, and TTS
• Secure user authentication and encrypted data sync across platforms
• Deployment scripts and brief technical documentation so I can maintain and extend the service

Acceptance criteria
• Latency for voice queries under 1.5 s round-trip in normal network conditions
• Accurate intent recognition on common personal-assistant tasks (≥90 % during user testing)
• Consistent conversation context preserved when switching devices
• All code passes a hand-over review and includes unit tests

If you’ve built conversational agents, worked with platforms such as Dialogflow, Rasa, or custom Transformer models, and have shipped cross-platform mobile apps, I’d love to see what you can do.

Resources are expected from in and around Chennai. Short term contracts selected candidates must be ready to work on premises
