Aury Care GmbH 🇩🇪

Fullstack developer for Aury, an AI-based psychological counseling platform developed with psychologists and therapists in Germany. Aury offers a structured stress-management course and check-ins for quick support in between — confidential, anonymous, and secure.

Key technologies

• LiveKit for real-time voice-to-voice AI check-ins — a streaming STT → LLM → TTS pipeline with turn detection, so conversations feel natural instead of walkie-talkie
• LangChain for agent orchestration, Langfuse for tracing and reviewing LLM runs in production
• Express.js backend, with Google Vertex AI serving the underlying models
• Autonomous agents for auto-QA that test actual LLM conversations end-to-end, not just fixed input/output assertions
• Partner testing through mocking — simulated integrations, simulated conversations, and simulated content recommendations — to validate the platform without depending on the partner's live systems
• Complete unit, integration, and end-to-end test suite

Key responsibilities

• Architecture design and ongoing improvements
• Handling partner integrations, working directly with the partner
• Building new features — mostly on the backend
• Performance & auditing improvements
• Built an LLM-based auto-tagging script to label and structure large datasets
• Designed recommendation algorithms and tested them against a large set of use cases derived from user stories
