Ryvn

Ryvn is an AI assistant that acts instead of just answering. It's a set of backend services, an agent runtime and native iOS and Android code working together. I work across the backend and down into the native layer wherever a feature reaches the phone.

Under the hood

• Communication between the API and the agent runtime
• Live Activities and Android ongoing notifications that stay correct even when pushes are lost
• Streaming voice replies from the lock screen
• Faster chat start-up through parallel loading and per-user caching
• Secure file storage with long-lived caching
• Personalized prompts, abuse protection and safe handling of user credentials
• Background workflows for scheduled and expiring work
• Device integrations: Siri, share extension, calendar, health, contacts
